Oh I see my apologies. We are using Build #22 from https://hub.spigotmc.org/jenkins/job/spigot-essentials/.

We were also using Build #21 when we first updated to 1.12.1

The issues began once updating to 1.12.1

Yes I know well enough to use /spawner {type}, when I do enter the command that is the code which comes up in the console.

More particularly:

[17:35:13] [Server thread/ERROR]: Command spawner failed:

Followed of course by the issue causing it to fail:

This is all the information I know. I also know that when trying to use the individual spawner id's such as 52:52, 52:91, etc (all of them), they still come back as pig spawners as well.

I'm not one for understanding code or anything. But I can tell something is clearly up here. Curious if anyone knows what the problem is here exactly.

If anyone has a clue or has had this issue and fixed it, your help would be much appreciated

Why do you want to join? - I have been looking for a skyblock server forever because
my computer will not let me download the actual map, this server allows me to and it
is great!
