I'm currently playing MC Eternal and used Level Up! Reloaded to level the skill Green Thumb. It gives nearby crops extra growth ticks. After I finished it the growth time of a single crop was near zero. Then I fully skilled Green Thumb from Reskillable and the growth time is now like a little bit faster than without skills. Can I undo the skill from Reskillable or is this a known issue?

There's slash commands to reset your skills.
