I'm new to the forums. I'm having an issue that I believe may be related to scatterer, judging by a few posts I've seen on Steam about how it can contribute to missing textures or sound. In my case, engines no longer have plumes at full burn, nor is there any sound accompanying it. The only way I can even tell the liquid jet engine itself is working is by the red glow on the engine itself. Also, I feel this may be related to the fact that on Spacedock, there's a warning stating Scatterer is an outdated mod and "is not known to work with the latest version of Kerbal Space Program. Proceed with caution." I have the latest version of KSP, 1.7.1.
And just in case it's needed, here's a screenshot of my Gamedata directory with all my current mods.
