No have encountered that or had any problems with Cigar box but that doesn't mean much. A sim crash can be caused by a number of things. Especially in V4 only because all the add-ons used may not be compatible with P3Dv4x but we try to use them all and end up breaking things. (I do it all the time for testing things.)
IE: Depending on where you are flying, and AI traffic issues can cause a CTD or lock up as well as conflicting scenery pieces. Now I do notice that you have been flying charters in Hawaii (EFMM) and submitting via cigar box. While this should not be a problem all depends on your scenery stuff, AI traffic etc and which way your facings. A CTD in p3dv4 can be as simple as turning your airplane to face something - which translates to request to show a bgl scenery piece or call on a ai traffic piece and if not compatible (FSX native), poof p3dv4 is a lockup, ctd or not responding.
If you are using the HI scenery pieces with AI traffic some may be conflicting with v4 and or conflicting with FTX stuff or anything else that you may have installed for the area.
All to say that have to start by knowing where you were you flying and what is installed for at area? I notice that you have been in HI - EFMM (Charters in HI Cigar Box). If there, between what ICAOS is the sim crash, what scenery intall etc?
Or if this was on a RTMM-MFC leg? Which> Are the Tongass AI fixes and RTMM AI traffic fixes for P3Dv4 installed? etc.
All to say, not easy troubleshooting but have to know a few things to be able to figure out what is happening.
