Or not. But heres three bugs I've noticed: 1. In com view, light tanks seem to have a different weight(?) than in the vf. AKA you can't add the same amout of armor and engines. 2. If you change name in com view, you must type kill to get from it. Can't E it out. 3. NF Heavys. Try add a nuke + 6 layers of comp. Then the weight is in white but it says that I have too much weight when I try to build it. (Tank wars anyone?) If I find anything else, I'll post it.
The nukes sound like you're on a server with custom scripts. I like how it takes a 14megaton nuke to flip most tanks, I've seen a heavy on it's back, completely still, roll back over onto it's treads.
Thank you for posting bugs, check if you can reach this site http://www.empiresmod.com/bug_tracker/login_page.php make an account and use the filter function to check if your bugs have been reported already. If not, make a new issue. Be sure to describe it as best as you can and note that it happens in 2.12.
i've had that first one before. it is caused by a second vehicle load out (for me its usualy named default_2) suddenly appearing and being auto selected when you view it in the vehicles tab. not sure why it happens but you can just click on the load out button and select your regular one.
