I had repetitive crashes when I tried to rename a portal. The portal had it's name deleted for unknown reason. Renaming only worked when I removed the controller and placed it again (in another block). Also I couldn't open this portal to anywhere. Also I had 1 or two other types of crashes related to this, couldn't click any portality UI button without a crash at some point.

Probably yes? There were no one to touch it besides me, and it was public. This might be related to trying to activate portals that aren't long enough, don't have enough distance built to connect them.

Where you the owner of the portal?
