Guif0DA Do the relevant events use an OR block picking objects of the same type?
I've got a similar lag issue with an OR block used as a sub-event:
Family Variable = value 1
Family Variable = value 2
I'm not sure if it only effects families.
This consumes 50% of my CPU. If I disable one of the conditions the problem goes away.
@Ashley I think this is related to the bug fix in R143 ("OR blocks which were sub-events to ordinary blocks did not always pick instances correctly")
