A rather unusual bug, Arthur keeps trying to sell the red slime to the merchant, but the guy just doesn't want it...
Additional info:
The red slime is no longer in the "trade menu". only 8x green slime, 4x glass and a single bamboo.
I've recently made that stockpile specifically for red slime to help speed up the trading process.
I'll provide my save file if necessary.
Edit: To get around the bug, I simply destroyed the red slime the moment Arthur dropped it, allowing him to sell the other things. Thought I'd let y'all know incase y'all find yourselves in the same situation.

I'm just gonna assume they had some sort of argument.
