Some code things I found:
- The hacky swap has been replaced by swap for the default chests:
https://github.com/minetest/minetest_ga ... eade1db896- If you don't use the on_dig code, like in the default/nodes.lua, it is possible to 'double' your possessions. Try placing 3 chest next to each other, remove the outside part of the large chest. Then fill the middle chest, dig it, pick the drops and look into the leftover (half) chest.
Another solution could be that digging removes both halves or that the remnant halve of a large chest doest connect with anothe chest next to it.
- The formspec of the players inventory misses 4 slots?
Some other remarks:
- The large chest takes the place of the 2 normal chests, but offers 16 slots less of space. Is that intentionally?
- It's a nice mod however. You could consider making double locked chests and double 'other chestmods' chests.
