LD/ Crash to char select 1-2 x /hr

[cmd594]

I've been playing on my "vintage" MacBook using Wineskin for the past several months. Setup with the instructions I found here were a breeze and I've never encountered a problem.

I hadn't played in several weeks and decided to sit down for some play time over the past week. Each time I log in for my 1-2 hour play sessions, I will periodically go LD randomly (sometimes off by myself medding (motionless), sometimes while traveling (especially when I'm on a boat of course), sometimes while zoning, etc.).
My system is updated and my internet connection strength and speed is unchanged.

Any thoughts or suggestions?
Many thanks!
