ModuleEngines NullReferenceExceptions

[1something]

I am getting these NullRefs in my log:

NullReferenceException: Object reference not set to an instance of an object
  at ModuleEngines.ThrustUpdate () [0x00207] in <cf1abf6b50ac49c3b967fb61a43f1e5f>:0 
  at ModuleEngines.FixedUpdate () [0x0005c] in <cf1abf6b50ac49c3b967fb61a43f1e5f>:0 
UnityEngine.DebugLogHandler:Internal_LogException(Exception, Object)
UnityEngine.DebugLogHandler:LogException(Exception, Object)
ModuleManager.UnityLogHandle.InterceptLogHandler:LogException(Exception, Object)

UnityEngine.Debug:CallOverridenDebugHandler(Exception, Object)
 
(Filename: <cf1abf6b50ac49c3b967fb61a43f1e5f> Line: 0)

Based on my troubleshooting, it seems to be caused by Waterfall, specifically Plugins/Waterfall.dll, as it fails to show up if I delete Waterfall or the dll.

Can someone please tell me how to fix it?

I am running KSP 1.11.2 with 100+ mods on a Mac.
