Confirmed for 1.8-pre1, pre2 and pre3.

Also, I think the world border animation (the stripes going up) should stop when the game is paused, but I'm not sure and I don't know if this needs to be treated as a separate report.

Um, what? How is this possibly intended? When the game is paused, stuff shouldn't happen. World borders are often very important in custom maps. This bug means that if a custom map is paused, the timing desyncs and the map is sometimes completely ruined.

How would you feel if you paused the game, only to discover that creepers can still move while the game is paused? This is arguably even worse!

The world border is a server-side mechanic to restrict the area accessible to players. Servers are not supposed to be paused. Time is constantly passing on servers, therefore the world border is constantly updating. We might revisit this after 1.9, but for this release it's too risky to change (and potentially break) this mechanic.

KingSupernova 2016-01-13T11:28:14Z

Thanks for the response. I can understand why it's not relevant for servers. However world borders are also used very often in single player custom maps, and this bug causes serious issues with those. It's also annoying when testing out a multiplayer system in singleplayer.

I appreciate all the work you guys put into the game, and I really hope you find the time to make this behavior consistent. It is a serious thorn in the side of mapmakers.

This also happens in Single player, without opening LAN.

This issue still exists in Minecraft 1.19.4. The world border does not change color to match its status and players do not take damage until the game is unpaused.

Lolothepro29 2023-11-27T16:50:25Z

The world border is not freezable with /tick for this reason.
