Hello everyone.
With the 1.13 update, there was a big bug that can only be fixed with the help of admins.
If you had SPAWNERS STORED IN CHESTS DURING THE 1.12 - 1.13 UPDATE, they will all turn into Pig Spawners. So, DO NOT PLACE THEM DOWN, deliver ALL OF THEM TOGETHER to an Admin+ inside a shulker box so they can fix it for you.
The spawners that were placed in mob farms are not broken.
Any questions ask below.
