Some of our players have reported not being able to research things. When I try the box for researching just says "Can't research" -no matter what item I put in.

What do I need to do to fix this? All items are enabled to be able to research in the config file.

Edit: stone fireplace was researchable. Think the cost is off on the asault rifle. Says 12500 scrap but when 12500 scrap is put in it still says "can't research"

Nvm. The actual cost was set to 125000 not 12500, last 0 don't show on the research table.
