Greetings, Guys.
As I am the author of these missions (aka tambor198 over at the Ubiforums) or most of them I shall endeavor to get to the bottom of the ctds.
First, the Battle of Sibuyan Straits is not one of my missions. There is a mission called Battle of the Sibuyan Sea by a gentleman named Ishigami. Could this be the one being referred to?
Palau Gauntlet was made by Hazelwood. I shall do some looking and see if I can make any corrections.
The the mission that Lt CDr lare is referring to Planes For Rabaul is one of mine and I shall see if I can fix the problem.
Might take me a couple of days but hopefully I'll be back in a couple of days with three crash free missions.
