Summon Reaper AI freeze bug

Sometimes summoned Reapers' AI gets broken and it just stands still doing nothing, untill ordered to dash or it decides to consume a minion. I suspect this bug has something to do with overlaping of dash order and signal prey skill on top of it's own decisions to perform special attacks. Perheaps the IA code messes up queueing the orders when multipple different commands are requested in a very quick succession.
Clear speed with the Reaper alone is already very poor and this bug just makes the gameplay feel frustrating. GGG, please fix.
