4.11 General debugging

[CzechTexan]

I've had 4.11 (clean install) for a week now. Today while editing missions in the FMB, I loaded a new mission and it was almost blank - no waypoints, no objects, hardly anything showing but the green waypoint select lines were showing in several places.

I loaded other missions from other folders with the same results.

For the past week I've been editing missions and everything worked fine, til now.

I read a few days ago (on M4T I think) that this happened to someone else.
