With both mods, the game will complain about there no being "minable" in treegen.lua, line 176 or so. Explosive Termites adds detonations as tree entities so i fixed it by adding a check with string.match for "detonation" to the whole bottom for-loop (for i, tree_data in pairs(data.raw["tree"]) do). The fix is just a few lines below the "for". Pastebin link: https://pastebin.com/XR9i9uHK
I don't know if this breaks anything since i haven't used this mod before, but at the very least it gets rid of the error, and arborium + mulcher does still produce saplings and wood at the end so i guess it's fine.
