FFNx VS Cppkies

I use 7th Heaven with these mods and when I enter a battle and time gauge is full(I can use attack) game just crushes and has message like oopsie woopsie game died go there:https://github.com/julianxhokaxhiu/FFNx/blob/master/docs/faq.md Does someone know how to fix this issue, or what mod can cause it?

Also, keep in mind that many of the quality of life improvements like 60 FPS come from a single project, FFNx: https://github.com/julianxhokaxhiu/FFNx I guess it comes with 7th Heaven "built in" now but you could always try this out for another easy option.

Hope that FFNx stops being so focused on FF7 and give FF8 some love (there's some hope now that FF7 has a 60 FPS beta)

They still have long way to go: https://github.com/julianxhokaxhiu/FFNx/issues/347

There's a FF7 game driver called "FFNx" that lets you do that. You can read more information here. However, coming from their website, it seems that Reunion is actually using their own driver (Aali), so I'm not sure how that would work out.

Read the source code for existing mods (e.g. mine, Klattmose's, Omniscient Cookies, Cppkies)

Unfortunately, Cookie Clicker modding is still in its infancy. The current modding API is extremely minimal; think of earlier than Minecraft Forge. In fact, CCSE is the closest thing we have to Forge; CCSE-based mods are usually compatible with each other, but mods that are outside of this walled garden usually have compatibility problems. (We even have our analogue to Fabric!)
