ImmersivePortals is not compatible with the Reroll mod, crashes game upon startup

[guysimtheprinter]

Hi there. I have recently started an Origins server with a large modpack, and I wanted to add IP to the modpack. I went to test out the mod, to see if it worked at least on a singleplayer world, but I can't even open the game. Whenever I press the play button on the launcher, the game loads, then exits with the same crash report: exit code 0 with no report document. Before you ask, yes, I did try to restart the launcher. Same error. I also tried to launch the game with Optifine and OptiFabric removed from the mods folder, and I received the same error. For some reason, when I first did this before restarting the launcher, the following crash report showed up:

---- Minecraft Crash Report ---- // Uh... Did I do that?

What should I do? Let me know if there's any other information I should provide. Thanks,

Well, I know that optifine isn't the problem, but to get this out of the way, are you using optifine g7?

[guysimtheprinter]

Well, I know that optifine isn't the problem, but to get this out of the way, are you using optifine g7?

No, actually. Idk why I didn't think of that before. I am using G6. I will try with G7.

[detective-wraith]

Ok, because G6 is incompatable

[froyo4u]

I mean you were still crashing without OptiFine so there must be a bigger issue

[detective-wraith]

One problem at a time cat

[froyo4u]

please stop calling me that...

[detective-wraith]

Not the place for this conversation. Icoslation, it's most likely one of your mods being incompatible if switching to G7 doesn't work

[guysimtheprinter]

What I am trying to do right now is load ONLY optifine, Fabric API, and IP. Then I'll go through and try to figure out which mod is causing errors. And yes, the game does in fact launch now with Optifine G7.

[detective-wraith]

If I knew how to do a thumbs-up emoji, I would put it here

[froyo4u]

👍

[guysimtheprinter]

You can react with it :0

[froyo4u]

you can send it

[detective-wraith]

And I would try out dimension based mods first, such as better end, better nether, etc.. You never know if one of them changes something weird about the dimensions on a whim

[guysimtheprinter]

Okay, good idea.

[guysimtheprinter]

Well so far all of my dimension mods work fine with IP, so I'll be trying vanilla game stuff like walljump and other mods that dont add items.

[guysimtheprinter]

And all vanilla fix mods work fine, including Origins. I had a problem with REI that was unrelated to IP, and I will be testing that last.

[guysimtheprinter]

Found it. The Reroll mod (v1.2.0) is incompatible with ImmersivePortals (v0.80). The game works fine without Reroll in my mods folder.

[qouteall]

Maybe it's caused by that reroll uses com.terraformersmc:modmenu but IP includes prospector's modmenu. The two modmenus have the same mod id and may conflict
