That's a different thing in RagMod Reworked. I don't remember where it's at but you can find it in the RagMod settings.

i just found out how!
1st step:open the spawn menu
2nd step: click on ragmod on the very right of the spawn menu
3rd step: click the player tumbler server settings
4th step: disable the drop weapons option
(note: i dont at all take credit for finding this out i only found out that there even was a setting for the player tumbler in the ragmods tab with the help of radical) if it doesnt work then idk lol.
you can also turn off the drop weapons on ragdoll setting from the ragmods settings since player tumbler ragdolls u when u bump into something it counts as u being a ragdoll so maybe it is the ragmods drop weapons setting?

thanks
