The sidearm mod in the seasonal artifact (column 1, row 1 of all 5x5 mods) does not work. It will not stay selected, and we haven't been able to use it for weeks. (I think in the first week of the new season it may have worked, but not certain.) When the mod is selected by holding X, it appears to be activated by changing from dull to bright appearance (as usual), but the counter at the top that states how many unlocks there are available does not reduce (i.e. if there are 3 unlocks before selecting the sidearm mod, even after selecting it, the count stays at 3). When we exit the artifact screen and go back in, the mod us unselected as it was a moment ago, and of course this means we see unable to equip it for Barrier stuns using sidearm. I did a search of this help game issue forum and didn't see any topics on sidearm/mod. This is happening with all of my characters and with my partner's characters as well - not just my experience. Is this a known issue? When will it be fixed? Thanks very much.
