[14:24:05] [Server thread/INFO]: [VoteRoulette] Disabling VoteRoulette v3.2.3

the line in question in VoteRoulette.java is:

PERIODIC_REMINDER = Utils.transcribeColorCodes(messageData.getConfig().getString("periodic-reminder").replace("%server%", Bukkit.getServerName()));

Fixed that.

Next: AwardEvent may only be triggered synchronously:
