This is on a server, by the way.

It doesn't matter whether it has that color in it already or not, they always go into my inventory instead. Tested with several colors, in various dimensions, with a full and empty inventory.

are you holding the bag when you try to do this?

No. The bag is in my main inventory. Also, very rarely, it DOES pull flowers in automatically, but I am unable to notice a pattern.

I'm getting the same thing. Yes other mods installed (181 total) check p455w0rdCraft 2.0 on technic for list. No magnet or anything of the sort in inventory. I break them with the bag in hand, same result. No botania errors in server log. Only bauble is Extra Utilities wings ring. Plus TiC knapsack and heart canisters in TiC inventory.

does it does this when you have only botania installed?

Seems to be working ONLY when my inventory is completely packed full, but still not 100% of the time. Botania version 221, different pack than the original situation but same issue appears.
