A bug has been found in the anim blueprint compiler which results in split-pins on animation nodes within a state machine failing to compile. Any values being used to drive these pins will be ignored at runtime.
Moderate: Animation nodes within state machines will not behave as expected when split pins are used.
The issue will be fixed in the 4.26.2 release. The CL for the change is 15749279.
