Thank you Thanks for your reply, I created a cloned profile and played around with moving the esps and it seems I can fix the land issue by moving the MAS esp to the bottom of my load order. However this then adds a transparent area to the area next to MAS which the console tells me is related to undeath.esp, it also reshapes the land, so I understand that these two are probably conflicting and inspect them through the information - conflicting tab (thanks for the heads up here, this is very useful!) but all I can see is a few tamriel.dds overwrites by vivid landscapes. I then made sure everything was installed correctly and in the right order according to the guide which it is, and I have included all compatibility patches and played around with MAS and Undeaths load order in both panes moving one before the other etc. I then manually edited my load order to replicate that of Darth Marthias at https://modwat.ch/u/Darth_mathias/plugins still no dice :( I suspect this is something really stupid I have missed, im still new to modding but have learnt a lot using this guide, I also see that these mods are true core to the guide so they must work together, just cant figure out what the heck is going on! Cheers
