I believe I have identified a crash bug in Entrenchment. It involves the AI, frigate entity types, Squad definitions and Command Points.
Basically, it appears to me that if you have more command points on a frigate/cruiser than you have unique squad defs in place, the game will crash when the AI even starts to think about using it. The entity will be fine if you use this as a player, this is an AI ONLY bug.
I have repeated the crash in my own testing but some independant confirmation would be nice. I will then submit a bug report to the devs.
To quickly and easily test and confirm, you can do the following:
1) Create a new mod folder under your Entrenchment mods folder. Call it whatever you like.
2) Copy <Sins Dir>/Entrenchment/entity.manifest into your new mod's folder.
3) Create a GameInfo folder under your new mod's folder.
4) Copy an editable TXT version of one of the stock race's carrier frigate into your new mod's GameInfo folder.
5) Open the entity file for the carrier frigate and set maxNumCommandPoints one higher than it already is (IE 3 for TEC/Vasari, 4 for Advent).
-Fire up Dev Mod and load your new mod, it should load just fine. Start a game. Make sure that you have an AI using the race you modded the carrier for, set them to hard to speed things up. I would add a couple more AIs using the other, non-modded races just to be sure the game has enough activity.
-Set the game speed to x8 and wait. It should crash within a few minutes - once the AI using the modded carrier tries to go for carriers.
-DO NOT help the AI along. This crash ONLY happens when it's the AI who tries for carriers all by itself.
-If you want speed things up, set the pre-requisites to 0 and lower the costs of your modded carrier so they are accessible right off the bat. The game should then crash within a a minute or two, if not a few seconds.
I have not had the opportunity to test this, but I suspect if you were to add a third (or fouth for the advent) squad def (say the combat/bomber squad for one of the other races) to your modded carrier entity, it would no longer crash. My theory is that it only happens when there are more Command points than there are Squads defined.
It took me over a week of hair pulling to figure out why my mod was crashing for no apparent reason. This seems to be the cause. If you can confirm this crash bug, please post in this thread and let me know.
