Mods that change the starting level of your skills

[killerbunny51]

Can mods that change what level your skills start at cause problems or crashes?

ANY mod can cause problems or crashes, regardless of what they do. Granted, the bigger the mod or the more it changes, the more likely problems or crashes will arise, but there's still a nonzero chance of even a small mod causing your copy of Skyrim to crash because something unique to your PC's build (software, patches, parts, etc.) just doesn't like it. However, the risk of innate problems/crashes tends to be small even with large mods, and when problems/crashes do happen, it's usually caused because two or more mods you have are conflicting with one another.

 

Now that's out of the way, it depends on the mod, and what other mods you might have. However, the biggest problem I can see (assuming no other mods) is that, unless the starting skills have been balanced properly, you may not reach the soft level cap of 81 without having to make a skill or two legendary.
