Thanks, I didn't get to report that in time but I bumped into that issue about an hour ago when I wanted to try the latest commits. :)

My game crashed when I was mining coal, then I joined kay27's server and the server kept crashing when I killed a wolf or tried to pick up XP from fishing. And there was another player, so that was probably another "crash source".

This is due to your earlier commit:
cfc86bcf3d

It also causes crashes when trying to sleep & eat; reverting your change fixes the crashes in all 3 mods as expected.

Attempting to sleep in beds crash:

get_velocity() doesn't work in 5.3.
it should but...
i have a wrap for that but not sure whether it good or not: local velocity = player:get_velocity() or player:get_player_velocity() or {x=0,y=-10,z=0}

Ok, I did not expect minetest to be that broken. Do you currently have access rights to this repo or do I need to merge it for you? If so, I need to know how I can pick up a single commit.

Thanks. Wussy had revoked the rights, so you are the only one who can help him to fix critical bugs in master.

I don't know whether 5.3 broken or it must be so (?), minetest issue tracker keeps silence about that too...

I know what happened. You asked about MT 5.4 compability in the other issue, so I tried it out in MT 5.4 and noticed the warnings. In 5.3 there is get_player_velocity and get_velocity returns nil for players, and in 5.4 get_velocity and get_player_velocity both return the velocity, but get_player_velocity is deprecated.
