recently (1 month around june 17 onwards) unturned has stopped loading mods correctly.
i have ran each mod individually with the same results, (e.g item supply can't find spawn table) or unable to reach spawn table.

then as i was looking through the error logs i found this.
Caught exception while populating (system files-> mod.dat) missing blueprint type
at SDG.Unturned.ItemAsset.PopulateAsset (SDG.Unturned.Bundle bundle, SDG.Unturned.DatDictionary data, SDG.Unturned.Local localization) [0x00603] in <97242534d6e24fe7a638e008e68eac19>:0
error parsing (mod file locations) mod.dat ""duplicate key "Blueprint_2_Type" on line 37 replacing existing value "Ammo" with "Ammo""

im like WHAT THE ACUTAL HELL.
why is it unable to parse?
why is it replacing a value with the same value?
why does it do this to EVERY MOD. AND NEW MODS
i have tried with the newest workshop mods

TLDR: after the june 17 update everything is broken, could be new update workshop outdated syndrome. but as far as i can tell, nothing new was added AND it shouldn't be causing a parsing error.

any advice on files to delete or repair would be great
