So I have a repair pack, I use it so it has ~10 durability(out of 300) remaining.
I repeat this 19 times to get 20 all basically consumed.
I put them into the condenser making sure not to merge slots(or the game would merge them into a single item with ~20 durability).
Then with 5% quality I should expect it to produce one item with about 10 or 310(because uncommon has 600 durability not 300 so it gains 300 during upgrading) durability and the quality level above.
Instead I get a single item produced with 600 durability remaining. The mod forgets the durability was used.
I suspect a similar thing happens to science packs with their science capacity, but I haven't been able to replicate yet since it's much harder to get a larger number of them almost, but not quite used up.
