First of all:
You got a realy nice game
I got the same "Crash to Geo"-Bug like those listed above.
Version is: UFOAI 2.3 R24791 Developer's Built
********************
ERROR: LET_PathMove: Actor movement is out of sync: 115:140:0 should be 122:140:0 (step 1 of 1) (team 1)
********************
Shutdown server: Server crashed.
I also saw this line in my consolelog:
==== InitGame ====
SV_AssembleMap: Map assembly 'craft_crash_fighter' not found
Hope this helps you to solve this Problem...
