Bugs

Hello, maybe it’s worth checking why is this PG not working on 5.0. Sorry, I couldn’t name better the topic, I don’t have a clue what component may fail, I’ve just came around this PG and spotted the problem.

See Heat map on solid particles - #12 by Evgeni_Popov, it was more a bug of 4.2 than of 5.0.
