While the original problems I made this thread about are resolved, there are other issues that have come to light that I was hopeful that someone could help me solve. There are four main problems that I've identified, which I've listed below:
1. Faulty engine glow graphics (See Screenshot 1 for example)
-The little white line behind the engine glow will rapidly and sporadically appear and disappear behind every single engine glow graphic in the game, so I'm pretty sure it doesn't have to do with the engine glow image files.
2. Incorrectly assigned ship debris (See Screenshots 2 and 3 for examples)
3. Absent scenario selection menu background (See Screenshot 4 for example)
-From what I've seen, the background is present in every other menu in the game, just not the scenario selection menu for some reason, so I'm pretty sure the problem doesn't have to do with the image file.
4. Absent comm messages ([COM_HITBYSHIPDETONATION] and [COM_STARTCAMOFLAUGE])
-The text lines in question are present in the comms.ini file, so the problem isn't simply due to them not being present in the file, and while I know many messages are displayed in the comms window in game, I have never, EVER seen either of these two show up, even when the appropriate action trigger occurs to make them be displayed, and since I am certain that if it was working correctly, I would have seen one of them show up at least once, I know something is up.
By the way, I've already sent emails to redmarblegames.com about this problem, but since they're taking a while getting back to me, I'm hoping someone here might be able to solve these issues quicker. If you need anymore information, just let me know and I'll gladly provide it.
