Is this just one entry?

The mod `ripplegates` (likely the mod id; the mod name might differ;) caused an exception. Try disabling that.

The mod provides debug information, You see the source code file (`RippleGates.cs`) and line (`205`) where the error happened. That is useful for the mod creator.

```
NullReferenceException: Object reference not set to an instance of an object
RippleGates.RippleGates.Player_NewRoom (On.Player+orig_NewRoom orig, Player self, Room newRoom) (at StreamingAssets/mods/ripplegates/plugins/src/RippleGates/RippleGates.cs:205)
[...]
```

there is no mod of that name, nothing related to it, it may be something to do with watcher itself

What mods do you have enabled?

You can send the other logs as well (the file LogOutput.txt has the mod list and some infos about them, for example).

In case you missed it. I was refering to the section from the mod description titled BUG REPORTS.

"BUG REPORTS
Please post bugs on the Rain World Discord[discord.gg] server in the channel '#modding-support' (ping me @schuhbaum) or on the mod's GitHub page under Issues[github.com].
Describe step-by-step how to reproduce the bug. Drag & drop the files 'consoleLog.txt', '\BepInEx\LogOutput.log' and 'exceptionLog.txt' (if it exists) from the folder '\Steam\SteamApps\common\Rain World\'. These logs get deleted or cleared when you launch the game. Send them after you encounter the issue."

sorry, but i don't have discord

You can copy&paste the content from `'\BepInEx\LogOutput.log' in here.

I saw two people on Discord having the same issue. But they could not find out what RippleGate is. One suggested two mods but I just tested and they don't install that. Maybe some region mod that loads additional mods is the cause.

Found it.

"id": "ripplegates",
"name": "ripple doesn't disable karma gates",

Disable that mod.
