Thanks for the detailed reply, nice to know even small and niche bugs like this get sorted eventually.

Mods used: Nullius and Editor Extensions only (+dependencies), reproducible in a new editor extensions testing scenario (see attached save with replay record).

The bug is seen here, pasting from the top chem plant onto the 2 bottom ones before (left) and after (right):

Some thoughts on this matter:

Ideally, a power generator entity that burns fluids for energy should not, as default behavior, destroy fluids with no fluid value. Ideally it wouldn't even be allowed in the fluid box but absent that, it should at least not magically destroy it.

Thanks, I'll try opening a bug report there then.

EDIT: thanks to the devs the issue appears to be fixed for 1.1.7

Adjustable inserters don't seem to flip correctly, neither picup/dropoff orientation nor near-inserters:




Note that fixed-orientation items (e.g because of pipe inputs) give a "this blueprint cannot be flipped" message.
