since you aren't currently using your config class you should remove (at least) the @Provides block in order to not show a settings icon beside your plugin in the config panel

[xetrics]

I wasn't sure if the config implementation was needed for the plugin to function properly. I've removed it for now.

for completeness, could you remove from availableVeins upon the WallObjectDespawned event

[xetrics]

I cannot, due to how MLM works. Veins are removed and readded on alternate ticks.

no worries, the availableVeins.clear() on LOADING gamestate (& this removal) should be sufficient (if not you can consider WeakHashMap & newSetFromMap)
