This problem has been occuring with the last several versions of your mod after the 9.3 game patch.
About 20 - 25% of the time that I try to enter battle while in a platoon, tank racing, or in a stonghold group, I simply do not load. I find that if I exit the client and restart it it usually load into battle. Of course, this usually puts me into battle sometime after everyone has moved off cap.
I currently have v.3.9.15_93 installed. I did follow your instructions for "all necessary steps towards safe installation."
Thanks for putting together a great mod.
