Last night, I was pushing first season farming. Start to build two 1x3 plots, while the second is being built, assign seeds to the first, while it is being planted, assign seeds to the second, when the last tile is being planted, build two new 1x3 plots, plant first, plant second, repeat. Surface or underground depends on what seed are available to plant at that moment, so what gets brewed, basically. Once it was too late for planting, I just filled all the planned areas with farm plots, occasionally going back to assign planting with shift-enter.
In late month 3, I happened to glance at the job list, and was amazed to see dozens of "Plant Seeds" jobs. I watched her, and sure enough, right up to the last day of winter spring, my Expert Grower was happily planting seeds that would be deleted the very next day. Here it is, 3/28, there are 18 plots with at least some green, most with all 3 green, and once the day rolls over, they will all be gone.
It's probably happened before, but never noticed it because this is the first time I've so aggressively plot-spammed, building much more than I'm going to be able to plant with just one grower.
1. I thought late planting was fixed in DF2014. An answer on about page 11 says so, but has it cropped back up?
2. If it's level-based, how good does she have to get to not make such a rookie gardener mistake? Better than Expert, obviously.
3. How do you deal with it? Forbid seeds at the end of the second month, and repeat as they roll out of the still/farmer's workshop, then release them first day of the next season? Is there anything a little less tedious? I don't really want to take her off farming, but...
[EDIT]
Oh, crap. When I said "winter", I meant "spring". Right now, it's just hard to think of January as "spring". I hope I didn't confuse anyone when I said "month 3", but then called it "winter".
