#1. Not sure if it's me or some weird glitch. I have this cave spider spawner and in a 3x3 cube of glass with glowstone on all sides of the spawner (see image). Normally this is enough to 'turn off' the spawning but it still spawns. Is there something I'm missing or shouldn't this spawner not spawn right now? #2. Again as you can see from the image above, I'm digging out this huge thing. 64 blocks in all directions from level 60 to bedrock lol I'm using a beacon with Haste II and Eff V picks so it's super fast. Sometimes though when I move forward I start glitching out. It's like I'm stuck on something but nothing is there. I exited the game and came back and there we're blocks there now like they we're broken at all. Are they being mined to quickly and the game doesn't remove them fast enough? Maybe something I can do to prevent this?
