Custom Maps + Mod Issue

[Creakz]

Hello to you all in the Minecraft Community.

 

Before I state this I would like to thank every single one of you who take the time to read about my issue and also comment to help resolve my issue.

 

 My issue is when I have a custom map installed, it crashes, and also I have no clue how to have mods on a custom map, for example, the mod "ApocaBuckets" I would like to use when using a custom city map because when I attempt this, it just crashes when I have it in my saves folder. Everything from the map file was successfully exported to a custom folder and then dragged over to the saves folder.

Provide a debug.log? Adding mods to a map is just as simple as loading the map, unless the map is doing something ridiculously resource heavy that prevents anything from loading.
