I'm a big tank enthusiast and I create allot of tank vs. tank custom missions and so far things have gone as I've expected. However suddenly I am having trouble getting tanks in the mission editor to fight each other. I found turning up the difficulty worked at first but now the problems are getting worse. This applies to new and old missions that have worked fine in the past Usually they either fire a shot then stop, track me or an ai unit with their main gun but do nothing or simply drive past without doing anything then stop and move their turrets around and do nothing, they also seems to track then shoot each other rather than me or one of my allied tanks. I’ve also been killed by friendly fire every time I play a mission and the game will crash after this These problems apply mostly to enemy tanks but friendly tanks are also malfunctioning. What is the problem?
