I've been playing hissho and vaulters, and whenever I colonize a system, it randomly decolonizes a certain number of turns. I'm getting very annoyed with this glitch and don't feel like playing the game because my colonies are perfectly fine, and then they decolonize for no reason. I already sent a thread about this, but I'm sending it again because I can't find my original thread. Please fix this so I can play the game normally again!

The thread you hijacked for the issue you have is exactly below yours ("Random UI freeze") or to be found here: https://www.games2gether.com/amplitude-studios/endless-space-2/forums/114-bug-reports/threads/28344-random-ui-freeze?page=1#post-351410

I still did answer to your "bug report", so you should be able to stop decolonizing on your end. Happy gaming.
