Hey Beartastic,
That is a new issue. The day shouldnt play a role in the issue. The issue might be on my end and Ill look for a solution. I apoligize for the inconvenience.
Thank you.
I started playing on the 0.63 version and the workaround for me so far has been to put the ingots on the shelf for a while until I make a few more weapons and if I try the ingot again later it works. Though there's no consistent time or number of weapons between the bug and it working again it seems...
