No warning message when entering a savage group that will only yield 1 chest

[Mirakumi]

dont think they can roll on it at all, just like in regular omega

I tested this, you are correct. They see the chest open up, but cannot lot.

Thus I assume they are there to 1) well troll.

Or

2) Genuinely To help out. Considering I joined to help clear - said 1 chest is fine. so yeah.

But mostly

3) They think they can lot and then find out that they can't and feel stupid lol
