OK, found a possible reason for the tanker, especially if it was a big one, since it sits between two quays, and was slightly toward the rear of the slot. Moved forward, and centered (hopefully) better. The airplanes have good routes for the most part, as do the ships. For whatever reason though, the game will ignore the routing, and the "assets" can and do wander off from where they are set. All of the "turns" are within reasonable degrees of curvature, etc., as well as being at good heights. Airpanes do have issues though when they go to attack, and will sometimes crash miles from where they "dove" for an attack. I find nothing wrong with any of the routing. One thing to remember when "zooming" about with the external camera, is that if your submarine is not within about 8.5nm or so, the "scene" is not entirely rendered, especially the terrain. If you go over roughly 20nm away, there may well be nothing. We also cannot explain performance hits at Truk. It has been extensively re-worked over the last four years, always paring down the amount of traffic there, and the only things recently increased have been the "docked" ships at various times from late 1942 to early 1944. The next (hopefully imminent) release does have further improvements in performance for the game, so maybe that will help alleviate some of the Truk issues. However, Truk also had extensive "terrain" changes to "dredge" the channels for ships to pass through, by previous modders, as well as the FotRSU Team, and that might also contribute to the little hiccups you experience in the area. High TC used anywhere near a "major facility", which Truk is, just like Pearl Harbor, and you will sometimes have to bring the TC down to the 128x to 256x area as the maximum. We'll continue to look into areas like Truk, and it is more or less the easiest place to check things out, as pertains to the rest of the mod, because a lot does happen there. Almost as much as what you'll see around Bungo Suido... Thanks for the info!
