This has happened frequently to me. Sometimes when I type /warp shop or /spawn in Skyblock 2 I would die immediately. i wasn't falling or even walking. My skyblock partner, TROYZORG, has also experienced the glitch.
It's a weird glitch. Jumping, flying, walking, standing still, just everything. Don't have anything in your inventory. Mmk?
Please use the correct format =) And also, I have experienced this too, dont worry, the admins will fix it
Um...no. The staff haven't accepted this, so you don't know weather or not they will fix it. So please stop posting "They'll fix it" on threads like this. You're not a staff, so you really don't know. Now, back on topic. I have only experienced this when I log into the server and spawn in the Hub. This hasn't been happening anymore, but its never happened on Skyblock...
Well honestly, I dont know if the admins will fix it, so you do have a point. Im just saying that they might :P
Don't know if I have to state this again... but Standing on 'half slabs', or having your Y coordinates somewhere in the decimal range, would make you suffer an undefined amount of damage. If you're asking J&H to fix that though, sorry to say that it's the skyblock plugin's original behavior, and it was set to do this.
