Issue Details

Platform:PC

Context:

Doing Delves

Expected:

An ability to go onto the next floor

Reproduce:

Here's what has happened: It was outrageous trovian delve and when i've defeated the boss (which was Shadowshroom King), i've decided to check his trophy to see if unique trophy has been added yet or not. It wasn't, but in the midway i've noticed that everything has disappeared and the boss spawner has "spawned" back. I've defeated the boss again (without timer) and... nothing has happened: the spawner got removed, as well as all traders, tools & portal to the next floor. And there were no message that i can't continue my delve, just... nothing. I had to stop delving because i got soft-locked.
