Upgrading or removing and copying assemblers can result in phantom items

Issue description

My depot failed to craft any more haul trucks after all the parts were delivered bar 8 red units, and strangely enough the dedicated assembler next to it was nolonger recieving any parts to make any more. This seemed to occur after I had deleted and moved said dedicated assembler, so the previous one that was unity-deleted may have 'put these 8 parts in the aether' so to speak.
Rather interestingly as well, the vehicle depot was holding onto 880 yellow parts that were not actually on the statistics list until after I deleted it, but this seems an unrelated other problem.

So tldr I have 120 total red parts on statistics, but only 112 of them exist (in the shipyard), all associated buildings and all assemblers were deleted, no dice, the remaining 8 parts dont exist

oh and unity cannot access these parts either, despite the button being available.
also possible that a phantom truck has them, but I would have no idea where to look for any this late in the game...

adding a console command to force a complete flush and recalculation of the statistic/global values would be good, since this also affects delivery via trucks and also seems to deadlock assemblers?

though similarly I have had other issues of using unity delivery with it simply not working, or only partially delivering the items, as opposed to the normal behavior [of there not being enough parts] of not delivering anything and making the error noise

sometimes this is because trucks are in the process of picking items up or delivering them, but sometimes this just does not work correctly at all until much more parts are made

so its entirely possible that the numbers of each item in my save file are entirely broken and I have no idea what the true values are until I delete assemblers and check stores and the shipyard

Would you by any chance have a save file before you deleted the assembler that made the phantom products?

unfortunately no, that would have been a few days back of autosaves before I discovered the phantom item count issue, I had essentially demolished and moved it out of the way of the path and queued up 5 more haul trucks, only to then realise a couple days after that said trucks were never completed, the building was still waiting for this last 8 non-existent parts

I just checked if the v0.5.3D update today added any exception logs for this, but there appears to still be nothing and the 8 items cannot be found.
Was there an exception log event added for whenever a unity deliver fails?
