Multilevel 200'/150' CCR plan gets "cannot decompress" on bailout at second level.

[fisker]

In the plan below, clicking the second level and trying to do a bailout on the second level (150') displays ;

"Error in dive at 150 fsw. Cannot Decompress. Gas does not have enough O2. Change your gasses".

I'm not sure which gasses I should change, and I'd think it should be able to do a valid bailout for this.

Hi,

Thanks for a very preceive bug report. I easily reproduced this and found the problem. You can probably work around it now by making small tweaks in your plan (if you can get away with that), specifically reg. depth/time for the second level.

The next release is "planned" for sometime in January, but I may ship a bugfix release before that with the fix for this.
