Acyclic throws exception when compiling with IDEA incremental compiler

[s-nel]

Periodically after saving a single file and attempting to run tests in IDEA, I get the following exception from Acyclic. Exception goes away if I do a complete rebuild. Exception is not thrown when compiling with SBT.

I hit this as well. It makes acyclic unusable because it occurs on every compilation after the first one after an sbt clean.

Any workaround for the issue ?
