Warzone Operator Menu Bug Fixed by Raven Software
New updates usually bring a few unforeseen glitches and bugs, especially so for Call of Duty. Warzone is notorious for its bugs and exploits, but the Operator page bug was thankfully quickly fixed.
The glitch would prevent players from accessing the Operators tab from the menu, preventing them from switching their Operators. This glitch isn't as game-breaking as others, since operators offer no real competitive advantage in Warzone.
There are still tons of bugs and glitches in Warzone. Combined with the omnipresence of cheaters, the game can be tough to play sometimes. Raven Software and Activision are working on improving the experience and have increased efforts at combatting cheaters, having recently banned 60,000 accounts. Activision will also expand their anti-cheat software.
It remains to be seen if that can keep players on board, as high profile content creators have been quitting and denouncing the game over its lax treatment of issues and cheats.
