Describe the bug
Hello author, this is a very strange bug related to the number of mods in the modpack. I created a modpack myself, but I found that once the number of mods (as shown in the bottom left corner of the main menu) exceeds 379, I cannot connect to the server, although local play still works fine. To address this, I tried removing high-risk mods like Sinytra, but the issue persisted. It wasn't until I removed Better Combat that the problem was resolved. Since triggering this issue requires over three hundred mods, it's impossible for me to check one by one whether other mods are affecting it. I will provide the debug file from when the server connection failed, as well as my mod list. I hope you can help me check if there might be a solution from your mod.
