mobs not dropping loot, at all

[absinth3]

So, I'm playing on a 1.20.1 server, with the 1.20.1-2.16.6 forge port of Chest Cavity, up until now I've no been having any issues, but I noticed that entities like sheep, cows etc. don't drop either their usual loot, organs or even experience, organs or enchants do not come at play here, I tried resetting my cavity, still no loot, killed with an empty eq and an unenchanted vanilla weapon? no loot.

Is this a config, server, version or client issue? If anything, what can I do to solve it? I don't know whether or not the bit of log showcasing the issue is required, so I'll post it in the reply below

and here's the beast of the log bit, it occurs for every entity hostile or not that I have killed :/
