Re: [NEEDS SAVES] No evolve option (ready to evolve)
I also encountered this bug, and the sell/undo fix worked. I thought it was worth noting two other things I found out for anyone dealing with this:
1. The bug also prevents cutting/splicing.
You can't cut or splice plants that are bugged in this way. Checking for this option is another easy way to spot plants that need fixing.
2. Travelling resets all bugged plants on the lot to piles of dirt.
Plants that revert to piles of dirt this way can still be fixed with the sell/undo method, restoring their proper growth state and other factors. This seems to be a handy way to identify which plants need to be reset, especially if you have a lot of plants on your lot.
My sim has level 10 gardening, but I don't have anything installed but the base game.
