Steps to reproduce the problem

1. create a world
2. join it
3. crash

Looks like the fault of another mod. I found Forge issue 5645, which points to an issue you created for the level-up-hp mod. Basically identical crash report, and I know my capabilities are not returning null.

For now, it looks like disabling mods to find the culprit is the only solution. One thing you might try is using NBT Explorer to look at what capabilities are attached to your player. That might narrow it down. That, or just wait for sargunv's patch to be merged into Forge, which will point to the mod at fault.

(edit) I suggest leaving this issue open until we get that patch.

Does this happen every time, or just occasionally? I believe this is a Forge bug. It happens to maybe 5~10% of launches for me.
