The LE version of SexLab More Creatures is seriously lacking in updates, and is no longer useable. There's an updated SE version, but no matching LE version.   I took the ESP from the SE version and edited it so that it works in LE. The main problem was water records in edited cells; SE has some water data that LE doesn't. There were a few other little problems, but nothing significant. When it came to the core content, there was no need to change anything at all.
