Hi, from a quick glimpse into the log I am not sure what it can be. I may have to synchronise with Blu or Malte, they may have an idea. Gonna dig deeper at the weekend, cheers, -

Ok, briefly double checked - the fluid cap and handler is pretty standard and should not cause this. As malte mentioned in the corresponding IE issue thread this may be related to another problem. I leave the issue open in case something has changed under the hood and a change is needed.

I think you can close this. Had the same crash when I placed an IE pump next to a pipe so it's not really related to Engineer's Decor.

Oky, thanks for the info. Aye, the problem seems to be related to something under the hood of ED and IE. Ty again for reaching out, cheers,-
