React Error in Console

[Riknesh]

I seem to be getting this error on console randomly.

[22:04:25] [Server thread/WARN]: [React] Task #369575 for React v6.614 generated an exception java.util.ConcurrentModificationException: null at java.util.HashMap$HashIterator.nextNode(HashMap.java:1445) ~[?:1.8.0_222] at java.util.HashMap$ValueIterator.next(HashMap.java:1474) ~[?:1.8.0_222] at primal.lang.collection.GList.<init>(GList.java:122) ~[?:?] at primal.lang.collection.GMap.v(GMap.java:142) ~[?:?] at com.volmit.react.api.LagMap.getGrandTotal(LagMap.java:36) ~[?:?] at com.volmit.react.api.LagMapChunk.getPercent(LagMapChunk.java:51) ~[?:?] at com.volmit.react.command.CommandTopChunk.update(CommandTopChunk.java:111) ~[?:?] at com.volmit.react.command.CommandTopChunk.access$000(CommandTopChunk.java:37) ~[?:?] at com.volmit.react.command.CommandTopChunk$1.run(CommandTopChunk.java:77) ~[?:?] at org.bukkit.craftbukkit.v1_14_R1.scheduler.CraftTask.run(CraftTask.java:84) ~[patched_1.14.4.jar:git-Paper-176] at org.bukkit.craftbukkit.v1_14_R1.scheduler.CraftScheduler.mainThreadHeartbeat(CraftScheduler.java:452) ~[patched_1.14.4.jar:git-Paper-176] at net.minecraft.server.v1_14_R1.MinecraftServer.b(MinecraftServer.java:1148) ~[patched_1.14.4.jar:git-Paper-176] at net.minecraft.server.v1_14_R1.DedicatedServer.b(DedicatedServer.java:417) ~[patched_1.14.4.jar:git-Paper-176] at net.minecraft.server.v1_14_R1.MinecraftServer.a(MinecraftServer.java:1075) ~[patched_1.14.4.jar:git-Paper-176] at net.minecraft.server.v1_14_R1.MinecraftServer.run(MinecraftServer.java:919) ~[patched_1.14.4.jar:git-Paper-176] at java.lang.Thread.run(Thread.java:748) [?:1.8.0_222]
