I'll be honest I only use Heaven on High for leveling and couldn't care less about the chests. I just say "lets do this fast please" at the beginning of a run and most people don't seem to have a problem with this.

Just now I was doing a run where even after I said this 2 rdms kept pulling stuff from other rooms looking for chests I assume, and I didn't say anything and just stood in the portal waiting for them to come back while I did stuff irl. If they want to do extra that's great for them, but then they waited until the boss room to randomly kick me out of the blue, which I didn't expect because they didn't say a word during the whole run.

I know that there's a way to see who you last partied with but I'm not sure how to get to that menu so I can block those guys and not have to deal with them dragging a 10 minute run into a 20 minute one again. If someone can tell me how to get to that menu I'd greatly appreciate it but also what are your thoughts on this? I thought I was straightforward enough about not wanting to spend that much time on a run but apparently not wanting to chase after chests was enough for them to kick me. Idk
