[Bug]: Something returning null

[HyperSkys]

What happened?

Also fire damage is a crap ton faster than normal and also the bot is still there for a few seconds so it'll spam the death message like 5 times.

The fire damage stuff was on another thread but I had to mention that because it only sent 3 spam death messages every time they died just because of fire.

[Legit4K]

You can test my #35 PR, I fixed the fire damage, idk about the death msg part tho

[Badbird5907]

I did mention fire damage on #24, you said you were using 3.0-BETA, can you try the newest one, 3.1-BETA

[Badbird5907]

actually, try the newest update/commit and tell me if you still can reproduce the bug: https://cdn.badbird5907.net/TerminatorPlus-3.1-BETA-NEW.jar

[HyperSkys]

I tried it, it fixed the fire damage being very fast but the death message still sends about 2-5 times

[HyperSkys]

depends on the tps...

[Badbird5907]

can't believe I didn't see this: ConcurrentModificationException... not a NPE
