I've tested this with numerous revive scripts (Psychobastard's A3 Wounding System, Chessmaster42's CWS, Farooq's Revive, Grimes' Simple Revive Script) and they DO work when hosted locally, but upon loading any of them onto a dedicated server, they are completely ignored and normal (read - instant with no revives) death mechanics take over.
I get no errors in logs.
All of the above scripts work fine if I roll back to the legacy version, with zero changes to the mission files (the only change made is the version of the game).
I am aware that it's not BIS's job to bugfix community scripts.
However, because of the consistency with which these scripts are broken, the reproducability of the problem, the fact the problem goes away with a client rollback, as well as the fact that other base game functionality has broken in this update (see the Arsenal calls, etc), I expect this is somehow related to something behind the scenes/under the hood that is broken, and whatever that may be should be investigated/fixed.
