It's not a bug. If you can't complete a season tree this time around, you can continue where you left off the next year. It's how it's supposed to work.
The current new season of the wolf is the last season in circle of "new seasonal trees" - the next season (season of the bear) will be the first one when we are expecting changes with "old trees will be back" rule. So enjoy these trees for (probably) the last time.
This is only partially true. It's only supposed to work for the last time. We are expecting "new rule" in the next season as it will be the first in new year with completely new seasonal trees.
ok, thanks for your answer
then i can spent my reward points without fear
as lexor wrote, i tought reward trees shouldnt be repeated, but thats coming next time
Don't expect this going into the next year, the only reason why we got last year trees this year is because CDPR prommised they would be multy-year then they went back on that promise at the start of this Gwent year, they got absolutely skewered for it by the community so they had to backpaddle and patch in the old trees.
But since then there has been zero communication about how this will work going forward to next Gwent year, and at this point it would not be surprising if all the trees from past two years will be gone forever after February 2021.
Personally I think that is a huge mistake as you lose a lot of cool art and all the Lore you unlocked in those trees for hundreds of reward points, and the trees should be persistent with each Season having a dedicated Reward Book page with all current and past trees.
You forgot about the upcoming Season of Love which will be the final Season of the Year of the Wererat.
