You can make some guesses (mods that affect drop locations is one) BUT a fast way is to:
- Install a mod manager, such as Fluffy's Mod Manager, if you don't have one already (link to Fluffy's below).
- Disable HALF your active mods (it doesn't matter which). Of course, keep anything required for other mods to work, such as HugsLib.
- Start a new game. Do the errors appear?
- If so, that half contains the error! Go back to step 2, until there's only 1 mod left (plus any required mods , still). That's the culprit.
- If not, disable the half you had enabled, re-enable the half you just disabled, and go back to step 3.
Please note that this can fail, for extreme conflicts and/or bugs among several mods. In THAT case, you'll simply have to go down your mod list, enabling a small number (say, 3-5) at a time, starting a new game each time, until you find the problem(s). It's relatively foolproof but astonishingly tedious with a big mod list; the above method works rather quickly, give it a whirl before you do it the hard way. Nine times out of ten, it'll pay off ^^' .
Note: If you want to check for conflicts with a specific mod/group of mods, simply keep that set of mods active the entire time. If the errors persist with all other mods disabled, this means
that set has an internal conflict and/or bug(s). You can isolate it using the same procedure.
