Hostile Mobs Spawn on Transparent Ice

Normally hostile mobs dont spawn on transparent blocks like glass and ice however something has changed. I have a transparent ice cave in the Soul Sand Valley of the Nether and im finding multiple Skeletons and even Ghast spawning directly on top of ice. They dont usually do it if i just sit there but if i leave the certain area to where the chunk isnt loaded or something, and then come back to it, they are everywhere! It looked like i saw some of the skeletons spawn in the air to sort of force themselves in as if they know theyre not supposed to spawn on that type of ice. It really sucks cause i cant access my nether base anymore, especially with the Ghast as theres such high risk for them to blow important things up. Please help, this is happening in the overworld too it seems.

Mobs have always spawned on ice. In fact, in frozen oceans polar bears are coded to spawn only on ice. Ice is specifically included in the spawn algorithm and is used in many mob farm designs.

The categories of โ€solidโ€ vs. โ€œtransparentโ€ are not based in the game code and do not fit neatly to a lot of combinations of block properties.

No i have had ice farms that never spawned hostile mobs on ice, preventing me from needing to place torches everywhere for safety. I remember even being in ice berg biomes where all the hostile mobs would only be on packed ice. Somethings happened, even the old minecraft.fandom site about spawn proofing still has it listed as a way to prevent hostile mobs from spawning, and a popular youtuber in the mincraft community named Ibxtoycat had posted videos of him spawn proofing his nether with ice before. Ive used it in my nether before, had an ice castle there for the longest time.ย ย

Edit: nevermind i see it was changed a long time in 1.13 tho i see it listed for just java i cant find bedrock. I play this game on and off and really didnt feel like it had been so long since i could use ice for no hostile mobs. Sad change that i dont really understand necessity of, thanks though.. apologies for your time..

Now i wonder what other transparent blocks have been changed to allow mob spawning. I hope leaves havent been taken out too. Do you know if two snow layers still works?
