Are arrows still saved in lichess studies on the lichess server? Looks like that's not the case!!

Dear Lichess Team, first, I want to commend you for your hard work and for everything you do. BIG THANKS! However, I would like to report one, hopefully temporary, problem.
Namely, this morning when I was working on some of my Studies, I noticed something that came as a very unpleasant surprise. Namely, it seems that LICHESS STUDIES DO NOT REMEMBER ARROWS AND MARKING ANYMORE!! That would be a shame because it is an EXCELLENT TOOL that many users, especially coaches, find INVALUABLE in learning or teaching their students. HAVE YOU STOPPED SAVING IT ON YOUR SERVER, OR IS IT A ERROR?
Thanks in advance for your reaction and reply.
Sincerely yours: Obad Andrija, aka FM Andro2.

I am also devastated. So much hard work to graphically annotate my studies down the drain it seems. Fortunately I've exported some of them to PGNs lately, so haven't lost everything.

yes this is very seerious error..... honestly affect the jobs of many Lichess coaches who need these tooll,..... taking Holliday gift from Children of Lichess.org Coach who believe in Open Source n Free Software (Libre Chess) ..... very sad theye must now use Chess.com which has more reliable...

Yes, I do love Lichess, and well I feel sick right now, as I woke up to find all the arrows on all my studies gone.

This also happened to me, but also all the arrows in other people's studies are gone.

Please fix this. Or at least that we can see arrows again and that lichess save them.

They should reappear after the next server restart.

Yes, very necessary to fix.
