Częste "crashe" SK+

Witajcie.

Co jakiś czas SK+ wywala błąd:

[20:15:19 WARN]: [SkriptPlus] Task #39 for SkriptPlus v2.1.6 generated an exceptionjava.lang.NullPointerException        at com.w00tmast3r.skriptaddon.skriptplus.elements.virtualchests.v2.FormattedSlotManager$2.run(FormattedSlotManager.java:62) ~[?:?]        at org.bukkit.craftbukkit.v1_7_R1.scheduler.CraftTask.run(CraftTask.java:58) ~[spigot.jar:git-Spigot-1339]        at org.bukkit.craftbukkit.v1_7_R1.scheduler.CraftScheduler.mainThreadHeartbeat(CraftScheduler.java:345) [spigot.jar:git-Spigot-1339]        at net.minecraft.server.v1_7_R1.MinecraftServer.u(MinecraftServer.java:614) [spigot.jar:git-Spigot-1339]        at net.minecraft.server.v1_7_R1.DedicatedServer.u(DedicatedServer.java:273) [spigot.jar:git-Spigot-1339]        at net.minecraft.server.v1_7_R1.MinecraftServer.t(MinecraftServer.java:562) [spigot.jar:git-Spigot-1339]        at net.minecraft.server.v1_7_R1.MinecraftServer.run(MinecraftServer.java:469) [spigot.jar:git-Spigot-1339]        at net.minecraft.server.v1_7_R1.ThreadServerApplication.run(SourceFile:617) [spigot.jar:git-Spigot-1339]

Możecie wyjaśnić co to jest i jak to usunąć?
