go to common.rpf/data/ai and replace weapon.meta . do the same with update/update.rpf/common/data/ai
go to update/x64/dlcpacks/"name of dlc"/dlc.rpf/common/data and replace the files inside each dlc. do the same with
update/update.rpf/dlc_patch, the dlc_patch ones does not have dlc.rpf so just skip the dlc.rpf path.
