I haven't had any problems with this until this morning and thought I'd report this. I used my harvest/plow/sow tool to harvest and replant my tomatoes and all it did was harvest. I rechecked on it and it took me to the store, I chose tomatoes and it acted like it would plant them over the harvested unplowed plots...they were highlighted...but nothing.
i might note it is happening with some of the other crops as well but not all.
I already memcached, restarted, etc.

Sorry to keep adding to this but I tried reloading that farm and it showed it was planted after all.
All is well...thank you for all you do
