Why is my vault refusing to take in items it has room for ?
Hello, as the title implies I have an issue where a vault I use in my storage system refuses to take in certain packages despite having room.
Comparator to check how full the vault is
Threshold switch to check the exact values
From what I gathered online, my vault only has a 1470 stacks capacity (instead of 1620) because of unstackable items. However I don't see why unstackable items would prevent the remaining 300 or so stacks to be used. I found that I cannot go above 1148 stacks in the vault, as after that point, the packages get stuck in the frogport with the error message as shown in the following picture :
For the record I am playing in 1.21.1 with Create version 6.0.10 on a custom modpack.
