I'm sure you're aware of this but it really does need addressed.
Currently a tier 5 silo has the capacity for one stack and 68000 weight. A stack is limited to 9999. If you fill a silo (try to fill a silo) with uncut gems, you end up losing about 8000 in capacity because of the limit in number of items in a silo and stack size. (note: if this was a tier 6 silo, I'd be losing about 28000 in storage)
Two possible solutions:
1. Change the coding of silos to auto split stacks of like items when the stack limit is reached (like the vault does)
2. increase stack size to match the smallest bulk item in the largest capacity silo (this would mean increasing stack size to 80,000)
Anyone else have any thoughts or suggestions?
