Having the exact same issue, when installing SKSE I archived the data folder and installed with MO, but I copy and pasted the other 6 or 7 files (following a tutorial on youtube) so could this be the reason my SKSE.ini isnt changing my blocks memory?
Whenever I check the log it always says
256 256
Even tho its set to 768 (I think...currently in work and cant even remember) and its definitely not a text doc. I wanted to be sure and downloaded the SKSE.ini from nexus.
Yeah I know im rambling and everything, but im just making sure my/our problem is fully understood :)
