Stack trace:

Reproduce the reported game state involving Slicer, high speed antagonist, using client version 1.4.57-V2 and Java 1.8.0_201. Start by collecting the server or client logs, since the issue contains no stack trace; the work is done when the ClassCastException cause is identified and the game no longer raises it in that scenario.
