great feedback. there are some issues here we are working on, others I can suggest a fix...
T menu works fine now - we've been tweaking it to get rid of the displayvendor error message. Some people use T for other things (e.g. in ACE) so Blazes added it as a radio option. However the radio option comes up on all players screens - we need to make it client only.
the black screen is a pain. it happens usually to the last player to join, when someone else joins after them. not sure why. think it's part of the intro that needs making client only somehow.
AI air assets - On lingor it is too small so you get a lot of air traffic near base. There is a variable to reduce this but it is currently disabled. We will reinstate this soon.
AT character making a static weapon - make sure he has his PRIMARY weapon (rifle) equipped, if he has rocket or pistol out then it is positioned above the barrel of the rifle on his shoulder! (pointing up instead of in front of player) - We have also recently fixed the bug that makes you fly off if you accidentally mount it when it's being placed, but it's only a basic workaround for now.
For enemy troops the reinforcement times of 5 mins are actually a lot longer because a randomised factor is used as well. Set them in the parameters menu at mission start. There will be a working one for air units soon....
do you fuind the KA60 bounces on the rubble patch and keeps exploding?
