Guild Wars 2

Atleast in wvw (in all game modes).

I have +7% crit sigil, after I died they don’t apply..
I have to remove all weapons and swap them back to have +7% crit again.

Nope same bug also in pve…

After you died and use Teleport back u don’t get the sigils, you have to remove your weapons first to get the sigils bonus again

looks like its only for +7% sigil.

Do you have two weapons with these sigils? There are some stupid bugs in the game’s handling of duplicate sigils. See https://forum-en.gw2archive.eu/forum/game/dungeons/Most-optimized-sigil-combination/3772693 for an explanation.

Basically, if you ever equip two of the same sigil, then until you unequip both sigils, you need two of those sigils equipped to receive any bonus at all.
