In F6 and F7 mode, any kind of fluid or gas graphic got stuck (large graphic stuck in pipe while small graphic still moving)
No function issue.
Sorry for my lame description as i can't speak English well.
Steps to Reproduce
When some machines in the pipe system wasn't functioning (ex: gas outlet hasn't been built) This issue may be observed in this situation after pressing F6 and F7
This issue has not been confirmed by a developer yet.
