Don't do what I did
So I've started to correct this, but the bottom half is the problem area.
See at initial spawn, before init let's you do much of anything at all, gravity kicks in. And the result is these suckers start colliding all over each other. Well if you get enough collisions going on the system runs out of blockmemory. Which is very bad if that all happens before you even get logged in.
I haven't been able to get into my Experience today, and yesterday I could. So I scratched my head as I know it wasn't my code changes. Then I thought what if today for some external reason the system is slower responding to the init kicking in. Well collisions galore and no entry is what is likely happening.
Fixing it now to see if it solves the problem.
