Global Tick Counter Frozen - Wandering Trader (Or Other Mob Events) Not Spawning

Since 2022/2023, I haven't seen either of the reoccurring mob events happen in my world. There hasn't been a pillager patrol or wandering trader spawn in literal years now. I have made a copy of the world and check that mob events are set to true, I have waited around with lengthy overnight sessions with commands to check any instances of myself just being incredibly unlucky, but yet there is nothing.

These have happened in the past as I do remember having both patrols and the wandering trader be active within my world. But for some reason they haven't spawned for the longest time. There seems to be limited information on the internet about this as well, if any. I have also tried to put a bell in an active village to see if that has any impact (according to the Wiki). The only other notable thing, is for some reason, on one update years ago, the Ender Dragon respawned itself (including the massive amounts of xp and dragon egg) so this could have something to play with it as it is also a mob event.

I've had the world since 1.14 Bedrock edition at least, as it is using old generation on the overworld and the nether. I think it might be 1.13 the world was created however.

Edit: Other noted to add, it has been a realm before, it has also been on multilayer through Xbox Live, and a guest account has also joined through the switch (same profile, different device)

Edit 05/07/25: Still seems to be happening in the recent update after some testing

Edit 15/10/25: Still occurring. However I think this issue started happening in my world when all my villagers desynced with their work stations during one update. This was quite some time ago however

Edit 08/04/26: Still occurring, no extra information to give however. Still works on other worlds

Edit 18/06/26: Posting my test in brand new chunks. Pictures in comments.

​The Issue: Both Wandering Trader and Pillager Patrol events fail to trigger naturally, despite checking via commands that /mobevent minecraft:wandering_trader_event and /mobevent minecraft:pillager_patrol_event are actively set to true.

​The Isolation Test: Took a copy of the survival world into Creative and traveled 8,000+ blocks into unrendered, pristine chunks to remove old chunk interference (confirmed as thereare sulfur caves nearby). Set up a Repeating -> Conditional Chain command block trap to automatically track and log natural spawns (/kill @e[type=wandering_trader] into a scoreboard counter).

​The Results: Remained completely AFK in the fresh chunks overnight. The scoreboard remained at absolute zero.

​Conclusion for Developers: The bug is not a simple chunk generation error, a local mob cap issue, or a toggled game rule. The background global simulation tick loop/timer that handles random periodic world events has completely desynchronized or frozen on this legacy world file after surviving multiple version conversions.

​Side Note/Symptom: This same world file previously suffered a known legacy dimension-state error where the Ender Dragon duplicated on its own, leaving two legitimate dragon eggs.
