Been having issues with specifically downloading the (recently added I believe) Witblitz Contour icons. Only had the problem once 9.18 modpack releases. All other downloads seem to work just fine to include the icon's I resort to. Aslain's 3D icons with roman tiers. In looking into it, seems the name has changed in the .7z file that needs to be downloaded.
The attempted download file is "contouricons_Witblitz_NeonAlt_9.18.7z" but it seems that the name has changed to "contouricons_Witblitz_Neon_Aslains_9.18.7z".
Thanks for the work!
