Bug with t2 naval

The only thing that would be helpful at this point is finding a 100% repro case. That doesn't mean "when I play a game it happens 100% of the time", that means the fewest and exact steps required to reproduce it reliably in the least amount of time, preferably with a video showing the steps.

If you're interested in trying, I would install the server cheat mods and use an avatar commander to immediately build a adv naval factory and see what's the least number of units (or which units specifically) cause the issue.

Wasn't there a Nuke that looked like a Leviathan because of this bug that someone captured a pic of?

That pic looked cool

Literally everything being nanolathed pretty much has a teleporting leviathan in it. XD
