Crashed Skywalker Arduplane 3.40 when switched to RTL while the plane was in guided mode "Go to Here"

Hi, Crashed Skywalker Arduplane 3.40 when switched to RTL while the plane was in guided mode “Go to Here”

I can see that there is no Airplane firmware upgrade for APM beyond 3.40 and I can see that the bug was resolved in Arduplane 3.52. Can someone help for a patch for APM Arduplane 3.40 ?
