Prior to updating, I encountered wandering traders often in 1.16.5. But after hours of playtime in the new release, I have yet to see a trader show up in any of villages. Gamerule 'doSpawnTraders' has always been set to true and I am not sure whether I'm unlucky or if this is an issue in the new version.
I am able to get traders using the '/summon' command as a workaround but I'm not a fan of using cheats.

Steps to reproduce:
1 - Play in a 1.17 world for 3+ hours and hang around villages
