Another hotfix, relating to tools:
1) Fixed a bug where Remus is stuck in trying to complete a Copper Tool (after the highest tool tier is bought).
2) Fixed a bug where taking the said Copper Tool from Remus leads to a 'missing'/invisible tool.
3) Fixed a bug where an upgraded tool is never complete/lost in the making.

Related to #3, if your save file is affected and you bought a tool upgrade but never received it, you can send your save file to us and I'll fix it for you (let me know which tool upgrade it was). You can send your save to petalcatgames@gmail.com or on our Discord. I'll look into it and fix it asap! Sorry for the trouble!

Also received a report where Remus is stuck upgrading a Chroma Hammer. If you're still facing any tool-related issues, please send us your save files, and I'll fix the bugs asap. Thank you so much for your help!
