I have been working on producing fireworks that announce the start of nighttime. I had started producing fireworks with duration 3, white big balls. I had produced two batches; one of 19 and one of 8 (blame inconsistant gunpowder supplies). I had previously launched one from the batch of 19, as sort of a test fire, before going out for more gunpowder. After coming back, I produced the batch of 8, and tried to merge them with the existing stack of 18; the two stacks swapped instead, as they do when trying to swap different items. Eventually, after fiddling around with splitting the old stack, I was able to merge them all to a stack of 26.
I had found possible duplicates in a search prior to creating the issue; however, they were all closed as incomplete. Note however that I had only been looking at the summary field, on a search of 'MC firework stack'.
Possibly related (inversely) to
MC-5214. That issue was resolved as fixed; the "fix" might be causing this bug. However, it being fixed was merely an assumption.
If I get the issue to occur again, I'll hold the stacks and upload my level.dat file. I still have to craft 6 more to get my desired count of 32 fireworks; I'll craft them in groups of 2.
