Thank you so much man, I really like the skin, makes the Light Dragoons look so much better.
When I was installing skins I was mainly just stacking them hastily and might've made a mistake somewhere so I got a clean install and this time methodically went through the skins, and turns out they do indeed work, but after stacking many skins at once there seem to be some overlaps and bugs that result, for example your light horse skin and Coldstream greatcoat skin work just perfect on their own but if both are used at the same time then for some reason the Light Horse keeps only the hat but the rest of the uniform returns to its vanilla state.
That's the only such instance I've found so far, however I believe I've isolated why, its when you replace the troops text file, the previous one gets overwritten, for example on a clean install I put in your Australian Light Horse mod and found it to be working, now after putting many other skins, all of which have their own troops.txt, the lines get overwritten, in your Australian Dragoons troops.txt this line is to be found - trp_british_light_dragoon 12th_Australian_Light_Horse_(during_WW1) Light_Horse 0 133170176 0 0 6 0 0 - however upon checking my troops.txt now after several skin installs, the line is missing, so I believe that's why these things happen, not everyone has the same troops.txt file after all, but it doesn't seem to merge them it just seems to replace them so the changes made for one skin get overwritten in another and that's how you end up with these weird bugs or skins not working at all.
I guess one way to fix this is to take just the text that the skin requires from the provided troops.txt file and add it to your own troops.txt, I'll try that soon. There could be more to it than just the troops.txt file but that's all I can think of right now, all these skins work well on their own its just when you install multiple at the same time these strange bugs and errors occur.
