I'm not sure how this is possible. The line before then calls update_inventory which calls init_inventory which would set inventory. I can't see any paths by which it wouldn't work. Unless:

minetest.get_player_by_name(name).get_player_name() ~= name

hmmm

@rubenwardy I came across a similar issue once before #1722, not sure if it is related though.

Unconfirmed, can reopen if reproduced.

@ignaciomartinCFR Your report is invalid. capturetheflag requires 0.4.17-dev to work. If you look carefully, the source of this issue is denoted in the top most line, which states that the error's source is found in the crafting mod.
