Cannot Place IG Spawners

[belaleee]

I grinded like a mad woman to get the cash to buy 3 IG SPawners. After work I build a spawn area, water drop box type. I place slabs on the ceiling, and when I placed the spawner, poof, it disappeared. I built a cobble piller and placed one on top. Poof, gone. I put it in the middle, side, top, floor, everytime it disappeared. What gives? I even coppied the rooms I seen on other islands and it will not stay placed, it disappears and says I ready my fists. What am I missing?

huummmmmm i dont know but maybe you should submit this bug because this does not happen for me and i have a 150+ ig spawners grinder on skyblock

On Oasis the minimum island lvl required is 100, IF you don't have at least 100 it won't let you place it.
I recommend having a look in chat when you place it. It could tell you the reason there.
