Processing doesnt take items during processing

[Yello]

When processing some coal, I was able to process it, but I didnt get the coal coke- it would just finish and all I would get is the EXP. Logged off cos I didnt want to be accused of exploting, though no one could tell what was going on. No red text in F8 menu

Solved for next update.

Thank you for your bug report.
