RESOLVED: Auto producing rare units

Not sure if this is a bug, but are rare units supposed to be able to autoproduce? I know you can't produce them manually, but I found that it's fairly simple to autoproduce them.

I'll message the admins about it if it is an issue, but I don't want all of you greedy bastards exploiting it if you haven't already found out how to auto produce them.

Wow, this is serious, thanks for reporting! Should be fixed now.

Yeah. I had a group of 50 heavy tanks at one point. and the fact that they're free to maintain makes it even more severe.
