Keep in mind, you'll have to completely tear out and replace any already placed drills to see the changes. SE is weird like that. (Fun fact, it's actually possible to edit blueprints to change any inventory to any inventory size. You can have a connector with 10B Liters.)

Release 1.1.3 is out. Drill inventories increased to reflect tier. Thanks for letting me know. Your name is in the change-log.

Im enjoying the mods for the most part, only real issue im finding is that the compressed drill inventories dont seem to scale proportionatly so in my use case the 64x drill will mine but it wont collect resources since the inventory is too small. Love the mod otherwise makes clearing out areas for a base much easier at the very least.
