I'm not entirely sure how it happens, but for some reason when playing in multiplayer, if player A Right-click-and-drags around the same time as player B left-click-drags something, player A's rate calculator window ends up showing player B's selection.
Sounds weird, but considering I don't play multiplayer myself I'm not surprised the mod has those kind of bugs. I'll do a review of the code, maybe I can see what's wrong.
Ok, I can see the issue. The selection is not stored properly (not per-player and not restored in save/reload cycles). I've already fixed this in my current WIP version that I plan to release soon. I'd prefer to not fix it and instead focus on the next version that will bring a lot of features on top. Is that OK for you? I don't want to play down this bug, but you are the first one complaining about it.
