Regarding Ancient pheonix bug, I may be referring to a different bug but when you get the option to resurrect your pheonix and you choose not to, the pheonix stands up at least it's image, it is still dead and units can walk on the tile where it died. It is a graphical bug, it doesn't affect the game in any other way.
I've seen highterant lay an egg in a inaccessible tile (the void in gremlin battle).

Another bug I don't think has been reported is when evil beholders mind control one of your units it stays mind controlled for 2 turns instead of just 1. In my experience it should allowed to dictate one action of the target, not control it for 2 turns.

After 4th update, i have problem with sacrifice spell. Sometimes it makes critical hit on my unit, So, instead of sacrificing 5 paladins/knights it kills 10. Anyone with same problem?

What about *Valkyrie ability used* medal. I used them all, multiple times and there is still zero in the counter. I thought I saw this in the bugs section before, but now is gone, (not in fixed section either)

It works fine. They mean the "dialogue" ability used, not the "rage/valkyrie" ability used.

Slingers and Catapolt Orcs don't seem to be affected by fear
 

I've feared these guys on multiple occasions and they still attacked higher level units.

Wandering Scrolls no longer displayed
 

In the previous versions, whenever you used a wandering scroll, there would be an icon displayed at the top right of the screen showing what scroll is active and how charges are left. This isn't working anymore so you have to keep track of everything yourself.

Minor item bug:

The item Viking Shield has the wrong item listed in the Upgrade list. It lists Leather Shield as the item it is upgraded from, but it is upgraded from the item Shield.

In more technical terms:
The item barbarian_shield should change:
upgrade=addon2_shield_leather_shield,barbarian_shi eld
to
upgrade=shield,barbarian_shield


Found another minor bug:
The item Ogre's Club [ogre_club] has a part of its description missing. It says:
+4 Attack
Damage of Ogres, Trolls, Orc Chieftains, Jotuns, and Giants.
It should be:
+4 Attack
+20% Physical Damage to Ogres, Trolls, Orc Chieftains, Jotuns, and Giants.

The source line is:
dbonus=physical,0,20,0,-100,0,0

I can reproduce the "Enemy summoned phoenixes unattackable after resurrecting: Build 6250".

I'm playing 6250 and it only happen in the 1 Mio. Tavern battle. Maybe no other enemy ever used the phoenix, but it's reproduceable. I tried everything to aim on it, tried it over 10 rounds, but you can't, the phoenix "ghost" stay and nothing happen at all. The phoenix is invincible, you can walk on that spot etc. So try to end that fight as quick as possible, to avoid, that the boss summons phoenix. So I needed to cheat, to finally win this matches once, because this badass almost always call the phoenix and if that useless piece of phoenix attack one of my units, it dies (and become godlike) because of the counterattack.


BTW, here my minor (but important) item fix for the "Avrelii Gauntlet". I don't know the English name, in German it's named "Handschuhe des heiligen Aurelius". It's labelled as "Dress", but in real its a glove...all description clearly say it's a glove and by god not a glove looking dress. ^^

Find it in "items.txt", starting at line 23160 addon2_gauntlet_avrelii_gauntlet.
Change propbits=dress,rare to propbits=gloves,rare and done. Now it's really a glove and can be placed at the glove/belt slot.

I play with WotN v1.3.1.6250 and yes, it was still not fixed.

I am not there in my current game (6250/6250), but in my previous game (6249/6250) I fought it a lot and never had any problems with it. I did however always put one of my troops on top of the fallen phoenix once it was killed to prevent it from resurrecting. As far as I know the ghost phoenix only happens if you let it resurrect. If you place a troop on its corpse it cannot resurrect and the battle continues normally. Are you experiencing a ghost phoenix immediately after it has been killed (in which case it is a new bug), or after it has been resurrected (a known bug)?

After it has been resurrected, so it's really the same bug. I never though about that. Just put a troop on the corpse (before it resurrect) and the problem is solved. Thanks! =) But it's a bug and should be fixed someday. Can be very frustrating.

BTW, thanks for your item latest fixes, they're still present in 1.3.1.6250. And in my German translation, they just translated it 1:1, without the "+20%".
