Great! Thank you for the hotfix! The pickaxe drain problem is almost completely solved... but there is now a regression with an edge case: after this update, digging granite downwards with Mistral does not drain pickaxe/drill life correctly even though her base strength may not high enough in the vertical direction.
Also, the blueprint bug seems to be partially fixed: when converting a hard mode game to normal mode, if the blueprints for boots were previously found (prior to the updates removing them from hard mode), they appear as unlocked and are still craftable. However, the Alchemist's Pouch remains uncraftable under the same conditions. This is a very obscure bug (which is probably no longer possible to trigger), so it's going to be tricky to fix it.
