@Proteus I would really try adding “FSuspendRenderingThread suspend();” at the top of your function and see if it helps.
@anonymous_user_80eda73a That’s strange. I never had any problems with either of those and I’ve been using them reliably since many, many versions ago. I couldn’t do much testing with 4.19 yet, though. What little testing I could do, however, didn’t produce any errors related to those functions so far.
