possible solution force it into a moonlightresourcepack.zip afterwords?

What's that? Of you mean the resource dump debug folder that should always stay empty. If you leave that option on it will significantly slow boot times. It's only useful to check out the generated textures once

Huh it is always full after I start the game. ... you said its supposed to be empty but it is always full ...

default exported options for everycompat

[general] #Puts all the added items into a new Every Compat tab instead of their own mod tabs. Be warned that if disabled it could cause some issue with some mods that have custom tabs creative_tab = true #Allows the mod to try to remap and convert other blocks and items from other compat mods that have been uninstalled from one world. This was made so one can uninstall such mods seamlessly having their blocks converted into Evety Compat counterparts remap_other_mods = false #Clears out and remaps all blocks registered by this mod belonging to uninstalled wood types to air or oak wood remap_self = true #Makes dynamic assets that are generated depend on loaded resource packs. Turn off to make them just use vanilla assets assets_depend_on_loaded_packs = true #Creates a debug folder inside your instance directory where all the dynamically generated resources will be saved debug_resources = true

Last option should be false. I'll double check to see that's not it's default

is this issue related to Every Compat?

Closing due to stale.
