Hello on every instance of the mod i run, the night vision power flickers on and off constantly.

it also seems like no datapacks in general are working

also probably part of these issues is i frequently cant load into a world and get the error message resource root power missing or something along those lines

hey ive tried out the 1.19.2 version and it doesnt seem to have the problems that im experiencing so i was wondering if youd just try backporting 1.5.0.6 to 1.19 i think thatd work

Short answer: No.
Long answer: The changes mojang did for 1.19.1 & 1.19.2 are minimal (I had to change 1 method call over the entire codebase), most mods can and have updated, if you don't want chat reporting, have it be disabled on the server, or use mods/plugins that do the job. The changes forge did however, are required since they fixed Jar-in-Jar (which origins relies on since 1.5.0.1) in 1.19.1, as such Origins cannot be backported prior to 1.19.1, and since that version had a flaw critical enough to be hotfixed, there is no good reason not to use 1.19.2.
