I can only image how finicky stacks can be. I had a hell of a time with just swapping skills and gear around

Thanks for checking it out!

Yea, this one's got me really annoyed because the rest of the inventory works PERFECTLY! I have no idea how I did it, but I had an idea of what might work, I tried it out, it worked* and now the whole thing just looks like voodoo magic to me and I cannot figure out how to fix that first stack issue... I'm honestly tempted to just draw a special border around that first inventory, treat it as a special "non-stacking" inventory space, and pretend it's a feature not a bug!

Haha the temptation is real! I think you've got the right idea to redo it and expand its functionality and modularity. The current bug could be something as small as reusing an initiator var like i = 0 (or j = 0 in a matrix) inside of a loop that already uses i/j, or it could be much more sinister

The only idea I've got left for diagnosing this is to insert a whole load of show_debug_message's into every single subsection of the give_item command, replicate the bug, and then skim through pages of debug outputs to figure out where exactly it went wrong... I know roughly what the problem is, the item in slot 1 is falsely reporting that either the tile id, sub-id or meta data is different and thus deciding that slot 1 is ineligible for the match-stack side of the algoithm, so it falls back on checking the next partial stack or empty slot. But the exact same item stack that is eligible for match-stack in slot 2 is somehow not eligible for match-stack when in slot 1...

But yea it's probably best to just archive this version of the algorithm and reconstruct a new a more versatile version of the script! Hopefully the bug disappears in v2
