This mod can cause streaming issues so you have to expect that you get problems with models and textures that could disappear after a certain time.
I've tested this mod with all my retexture mods, custom treee models, Ash's vehicle and misc textures and my game runs stable.

I would strongly recommend to go to pc>data>cdimages and opening gtxd.img with OpenIV after installing the mod. Enable edit mode, open the file tab on the upper left corner and
defragment the archive. This will save a lot of file size, which makes streaming issues less likely to appear. Only necessary with the file replacement version of IV Lane.

I've created a version that works with FusionFix's modloader feature. I also removed some unfitting textures from the mod, fixed a few things and optimized it to reduce it's file size.
I've also added a parallax shader to all cobble road textures for more depth. I would strongly recommend to use this version over the usual one, because of the upper named reasons.
