Code in question: https://github.com/mt-mods/travelnet/blob/302e4252628837806d53654f2ad4dd52aaabbee8/formspecs.lua#L200-L203

Could apply the following diff for debugging purposes and report the findings?

The same thing happened a few times on the test server (test.pandorabox.io), so not a multicraft issue ;)

ServerError: AsyncErr: Lua: Runtime error from mod '*builtin*' in callback item_OnPlace(): /data/world//worldmods/travelnet/formspecs.lua:202: attempt to index a nil value
