After the latest update, there are some problems with particles. They seem to show up ON the UI. Pics to explain better:

Also, bubbles now show up above the navigation ui (shaman, room name, mice, etc) when someone dies above it (e.g: a mouse touches a lava ground and he gets pushed up a lot so he dies)

Yes I noticed this bug too, but it isn't too bad tho, those are just some clipping? layering? /i have no idea what/ errors, I don't think they will make the gameplay harder, but yes those need to be fixed too ^^
