Logged into hotel after a few days break, and my institute was at 100% but did not give me a . I put in an abomination and now it says research advances 140%!

A similar thing happend to me once: I received a gold vial in my lab for chopping up 5 guests but I didn't collect it for 2 weeks. When I finally collected it, the progress bar above the lab doors wasn't set back but instead kept showing 100% progress. I was able to send in an abomination and the progress bar said 140%. After the lab was done with the abomination, it was set back to 0% and I received another gold vial.

This happend with both of my labs at the same time, my guess was this is a minor bug related to the timing of the vial collection.

I've returned to the game after being away for a week.
Institute has 100% and there is no timer... I haven't even put anyone in there.

I've got an Institute which reads 100% also. Has read this for weeks, actually.
