Flowering and after: won't stack

[JP_Finn]

The plants harvested during flowering period and same plants harvested after the flowering is over: their leaves nor roots will stack.
Harvesting leaves of young plants stack with leaves of plants from flowering period.
Harvesting more of the plants the following years, leaves from young plants still stack with leaves from earlier years' young and flowering period leaves.

Seems like a tag from the plant of not carrying flowers carries over to other parts of the threshed goods.

It's been that way for many years. It's also the case with retted and dried stalks from Textilecraft plants. I haven't seen it carry over to the extracted fibers, though, but I probably haven't had multiple stacks of fibers at a time, as I've generally spun them directly after.

Fibers don't stack either. I got few stacks. Hopefully more in following years.
