Mod amount limit on Neoforge 21.1.133?

[Faalvare]

is there like a limit on how many mods i can add on a modpack?, for some reason, when i start adding too much mods, the mods start to crash, i tested it numerous times, i add one mod, doesn't matter wich one, a lot of my mods starts to crash on load, but then if i remove one, doesn't matter if it was the one i added or another one, it stops crashing, i know that there used to be a limit of object ID's but i tought that was fixed a long time ago, this is how the crash looks :

Can you provide the debug.log? There is an object id limit, but it would require ~2 billion entries for any given registry, which is just not a feasible number to obtain even if you added all the mods into a single modpack. You're more likely to be limited by the amount of resources your machine can allocate long before then.

debug.log is too big, here's the latest :

its like the mods are loading before their dependencies.

[ChampionAsh5357]

Do you happen to know the mod limit you're referring to? Also, would you mind testing without any performance-optimization mods? Finally, I would prefer the debug.log as that typically contains more information than what the latest would provide. You can upload it as a gist if necessary which should have a 100mb limit.

It's hard to know what specifically the issue is with so many mods working together, but I can spin up a quick test environment with a random number of mods and entries to verify.

187 seems like the in game mod limit, if i get 188 it starts crashing

Debug.log

in this one i enabled more than 187 mods and started crashing, then i removed one and it finished loading without crash, then again but other mods and same result.

im using curseforge btw, and now i updated to neoforge 21.1.136.

note that this crash happens on the structure_serialize_modifiers phase
