Something Weird Happening

Hello, Frost and whoever else reads this. I've recently noticed that after the last handful of updates there's been a strange bug happening in FT. It happens that sometimes when i change character the miniature of said character remains, despite me being currently using another character.
With love, Krakky Hoonter.

I would just like to add that I also "indirectly" suffered that bug.

I didnt notice it myself, but other people were seeing the mini of a char I had played the last on the table instead of the one from the new char I was creating. I, myself was oblivious to it as for me the mini was right. Updating the mini fixed it though (I did change the mini itself because it was still a temporal one during CC. I dont know if reloading the same one works).
