Getting error clipCount == internalClipCount

Hello I am currently on unity 5.1.4 and having some errors appearing that I assume are from an animator but am unsure what would be causing the issue. Within the editor I get "clipCount == internalClipCount" with no call stack. and on iOS i get a crash and the final steps of the call stack are

Exception Type: EXC_BAD_ACCESS (SIGBUS)

0 APP mecanim::animation::EvaluateBlendTree(...)(blendtree.cpp:879) 1 APP mecanim::statemachine::DoBlendTreeEvaluation(...) (statemachine.cpp:667)

If anyone could help shed some light on these errors it would be greatly apreciated.

Thanks!
