Done Mob Spawner not working anymore after changing the spawntype

I took a blaze spawner from the Nether and used the donor Command to change it to a slime Spawner. The problem is that no matter what i do or how i change the spawn type, the thing just refuses to spawn anything.

Edit: I changed the spawner Type by using the right-click menu

 

Is it not working with any mobs, including hostiles? If it flashes like its spawning but never actually does, then it may be the world mob limit is at max.

 

Well the thing is when it was still a blaze spawner it worked like a charm and my mob farm is also constantly spawning mobs - so i doubt that it is because of the mob cap.

 

the nether has its own mob limit, what other choices did you try and make it spawn, and did it flash like it was spawning them?

 

Did you try changing it to something else?

 

tried about every possible option for the spawner - refuses to spawn anything. (using it in the overworld btw)

 

Can you post the coordinates of it?

 

tried moving it around to no avail - at the moment it is located at x:-28679 z:13057 y:2

 

There is nothing at those co-ords when I go there, is this in the skyworld on your island?

 

The right click menu is there and opens up as it should. the problem is that once you use that menu the spawner stops to work. We passed the issue by using a draconic spawner now.
Coordinates: (this time from the m menu) (-28699, 2, -13058) 271'

 

ah and on a nother note - i think i accidentally disabeled skelly spawning on my island when i was toying around with the donator command. The problem is that i can't find a comment to enable them again.

 

The Owner of the island is QuantumEnder

 

thanks alot

 

I believe is the same command that you used to disable.

 

I think the command is:
/is flag deny-spawn <mobname> <allow/deny>
