Halloween Mobs still spawning after halloween did end

[korileafeon]

Hello everyone. I dont know whether Fear Evolved did end now or didnt, but the title screen is back to normal, the moon is back to normal as well and Dodorex no longer spawns. However, there are still Onyc everywhere, murdering all Argentavis with ease n.n. I have no idea whats wrong on my own small private dedicated server. Skeletal dinos and spiders do still spawn as well, but most annoying are definitively the Onyc. Am I the only one having this issue or does everyone still have these mobs spawning? If its a bug, is there a fix for it without ereasing the server files? Thanks a lot in advance ^^
