Describe the bug
Hi! I have recently been experiencing an issue where there are two mods which have duplicate mod ids (specifically the id "modmenu"). When I remove one of them, I get a warning telling me that 2 other mods depend on that mod. These mods came with either Cotton or Cotton Resources. Those are the only mods that I have installed besides Fabric API.

To Reproduce
Steps to reproduce the behavior:

1. Install latest version of Fabric, Fabric API, Loom, Cotton
2. Build and Run
3. See error

Expected behavior
There shouldn't be two mods with the same id ("modmenu") and there also shouldn't be two mods depending on both ModMenu mods.

Screenshot

Versions:

• Cotton | 1.0.3
• Cotton Resources | 1.5.1+1.15.2
• io.github.prospector.modmenu:ModMenu | 1.6.3-94
• io.github.prospector:modmenu | 1.8.4
• Fabric API | 0.11.1+build.312-1.15
• Fabric Loader | 0.8.5+build.199
• Yarn Mappings | 1.15.2+build.17
• Fabric Loom | 0.2.7-SNAPSHOT
• Minecraft | 1.15.2

Additional context
Before anyone asks, I have installed the latest version of the following libraries/mods:

• Fabric API
• Fabric Loader
• Fabric Loom
• Cotton
• Cotton Resources
• Yarn Mappings

I do not have any other mods except those listed above as well as their dependencies.
I have Java 11 installed and I am running Mac OS X 10.13.6 (High Sierra).

looks like it's because of Cotton, which is weird and frustrating, because cotton doesn't do anything with modmenu and I don't remember adding that. I'll remove it soon.
