This list contains popular mods that are known to have issues/conflicts/performance impact, some of which should be avoided.
4
Do not harass authors of the mods mentioned here, most mods mentioned here are either not maintained very often or simply abandoned

6
This list does not include every mod on the workshop that's known to cause issues, but rather most popular mods that often cause issues for new players
7
If some mod is not on this list it doesn't matter that it's safe to use, use common sense and caution when composing your modlists
8
Not all mods mentioned here are "bad" either, some are added just to inform users about possible lag or conflicts that can happen in some situations.
9
This list essentially combines Sam's (Outdated) and Dubs' lists with some additional mods I found on my own.
10
Second tab contains mods that improve performance instead, usually you want to have every single one of them installed

What does TPS, passive/constant lag, lag spikes and X ms mean?
13
TPS (Ticks per second) are different from FPS. Your game might be running smooth, but your pawns may be janky / slow when your TPS is low
14
Passive / constant lag means that the mod slows down, lowering your TPS even when no certain actions are being used
15
Lag spikes are when the game suddenly freezes for a short period of time, usually when a CPU heavy ability used or some action being done
16
TPS is measured in milliseconds - 1 millisecond is 1 / 1000 of a second. This means that if some mod takes 4 ms and base game takes 1 ms to run a tick, then your maximum TPS would be 200
17
By default, maximum TPS are: 60 at speed 1, 180 at speed 2, 540 at speed 3 and 900 at speed 4 with the Smart Speed mod
18
So, if 1 tick takes 5 ms to process, then your game won't be able to run much faster than speed 2 no matter what speed you choose. That's why even a few ms is considered critical amounts of lag
