Runtime error 11 in Mutation rates dialog

Start DB

Robots->mutation rates

Runtime error '11'
division by zero

Sprotiel:
Well spotted!

Welcome to DarwinBots!

I suspect it's a matter of the program trying to access the mutation settings of a non-existent species. If you select your robot species first, you shouldn't have problems.

Jez:
Hiya Frankle,

Thanks for letting us know about this bug. As Sprotiel suggested there is a way to avoid this bug for now but hopefully it will get fixed sometime soon.

Hope to see you again on the forum and welcome to DB!

frankle:
I tested it this morning with bots running in the sim, and it still crashed. Same repro. Has anyone else reproduced this or is it just me?

Jez:
I reproduced it before posting a reply earlier. The way round it is to start the sim, select one of the bots in the sim, then open mutations. (or so I thought)

Oh bugger, 400k cycles into a league match (DIN v The One) and managed to crash it by having another look.  

I don't seem to be able to consistently avoid that problem; it can happen with a bot selected when you select robots/mutations or when you r/click on a bot and open mutations, doesn't seem to make much difference if sim is paused or running.

I presume you want to change mutation rates while you have a sim running, I know it is possible, some people do it. We'll just have to wait until they tell us how...  

I only ever set mutations before start of sim so don't know how they do this, sry.

EDIT

In fact, I just thought I'd check on mutation rates before starting a new league match, it done the same thing, v nasty. May have to download latest version of DB again or restart pc just to make sure I haven't messed anything up.

EDIT

It seems I had to delete the bots from the 'loaded species' list and put them back again to stop the error occuring when I tried to open mutation rates before starting a new sim. Starting again with new bots and selecting a bot before opening robots/mutations seems to work again. Will see if I can find out what I did to make it go so weird.

Last EDIT

And now the only way I can get it to crash is by opening robots/mutations without a bot selected, V. Strange.
