Hemiptera Bugtracker at bugs.linux-forks.de

Using the master branch, at commit 5d372b1c. Running under Minetest 5.4.0 with Dreambuilder game. Other trains mods installed: basic_trains, disco_trains, minetest-moretrains

There a number of complaints from Minetest of undeclared globals.

Normally *all* variables and such in Lua should either be declared local to limit their scope, or be part of a unique namespace, such as an entry in a global table named for the mod.

Otherwise if two unrelated mods use the same global variable name, they will conflict, probably corrupting each others' states.

Here's what's shown up in my log so far:
