So now when you go to the editor most of the time the april fools day map 0 will play instead of the map you made. This is seriously getting annoying please fix this. I've gotten in confirmed by some others that its happening to them too. Literally just click Validate this Map and about 80% of the time it's map 0.

April Fools!

E - Jokes aside, I can't recreate this; and it's likely an April fools joke anyway :p

Is this supposed to be a joke or something brought by the admins or is it a bug

It's likely an April Fools joke.

If it is I'd like to hear a confirmation that it is, because I'm not any bit laughing at the fact that making maps is like near impossible with this. Sorry if I'm being a downer about a joke, but yeah, this isn't funny.

You're free to express your displeasure here, but like I said I can't seem to be able to recreate this. So, if it is actually a bug, it's one on your end or one that I'm free from. (Firefox + Linux, Flash 11.2.202.440)

If it's actually April Fools, it's just a day. It'll be gone by tomorrow. Not the end of the world.

E - I was actually able to recreate it now. The behavior doesn't seem like it should be this way but others expressed similar goings on elsewhere so I'm not sure. Either way, it's fixable by /morting so it's not like it's a BIG BIG issue. Just have some patience.

E2 - Have confirmed it's actually a bug. It's sad that Tig is so unpredictable you actually have to debate if it's a bug or a prank.

Fixed with today's reboot.

For future reference:
When you enter the map editor the blue screen you see is not an empty map, it's simply a blue overlay. In the background, map 0 is playing with yourself as the shaman (sometimes you used to see map 0 flashing on the screen very shortly when you click validate, not sure if you can still see it flashing nowadays).

You can test this by going in the map editor, clicking in the blue area and holding left. After about 3 seconds you drop offscreen beyond the death border and the death message appears "No cheese for you! ^_^".
Once you loaded your map successfully and go back to the editor, your map will be playing in the backround instead of map 0. Test this by making an afk death spawn and click "back to editor" after you played your map. The death message will play continuously because of the afk death spawn.

Map 0 is the default map for transformice and I guess when you are in the map editor and clicked validate once, the game replaces the default map with your own.
The april fool's update replaced map 0 (default) with a made trollmap, it's just that in the map editor your own map is the default now so it replaced your map with the trollmap.

Btw, the totem editor had the same issue because map 0 was playing in its background.

I think it's safe to say that this was a bug, an unintended side effect which was not considered or which has been considered but was not important enough to fix.

Has been fixed.
