I've been getting a weird bug in Robocode where it looks as though my bot does not run during a round once in a while. I'm getting no exceptions, no output.

In fact, Robocode itself is not even printing out the usual stuff. Any ideas? I've never caught this happening when I'm looking at battles run, I've only noticed it happening when its running fast minimized.

Here are the outputs from the bots. Notice that if a bot dies the system will output to that bot's log. But my bot is not getting output for that round, and none of my event handlers are getting run (so no profiling output from my bot for the end of the round)

Round 13 in these logs is the offender

My Bot:

Notice no system output for round 13.

Can't understand the cause or reason for this. Is it my bot? Is there some robocode bug?

Any thoughts?

Which version of robocode are you using? It seems that it’s a known bug of robocode 1.9.2.6, which is fixed in 1.9.3.0

Interesting, I am using 1.9.3.0. I guess the bug was not properly fixed?

I made some changes to my bot and its no longer doing that issue, so it must have been something my bot was doing but not sure what due to the lack of output!
