When I have Item Lore Stats Installed the fall damage for players is very messed up. Players take multiplied damage from falling and it is even enough to kill a person from a 4 block height.

What server version are you running? The current version of ILS supports 1.10

So it doesn't support 1.11.2

I can confirm, when I have ILS installed in 1.11 my players die of very little height

It must be another change that they made in 1.11 but I'll have a look into it and try and get it sorted for the next update.

I can confirm to having same issue .

I've just tested this on 1.11 and it's working as intended.

Have you changed anything in the config?

That's what happens for me which is working as intended. If that appears to be too much damage for you then you can change it in the config. If you look in the config under environmentalDamage, and then fall. You will see that the default value should be 12, that's 12% of the players health lost per block that they fall.
