4.12 development update discussion and feedback

[6BL Bird-Dog]

On Hyperlobby many are trying to host Coops but finding bugs with missions have set crt=2 to avoid mods joining and causing the anomolies.
Unfortunately we recently found out due to ever increasing weird hapenings in game that if a client joins a server and has wrote additional text in front of the CheckRuntime=2 line in the conf.ini ,I wont quote it here,that clients with mods can still join.
Can this be rectified in a patch or in 4.12 please as there is no concistancy in game play for those trying to run the official version ?
