This might be a case of bad prefix selection if that happens, but the blame likely goes to Red Carnelian, as we comply to the general measures that mods like this go under, while there is no entry by Red Carnelian.
Or the fact that no such thing was made.
PS, you are pointing to a DSotSC thread from 2005, updated last 2012, while this version is from 2017 to 2020, so... it's definitely not the same, and Stones of Askavar still seems to be a mod that overwrites both vanilla & mod files without any regard of actually patching files, so any mod composition that is made needs to take that into account and move the whole mod into patching format ... say, if memory serves, things like the dead BWP & BWS once did.
PS, the version you refer to is the (non-Enhanced Edition) BG1 version, while this is specifically the BG1EE, EET and BGT -only versions of the DSotSC. That same forum has also the old Tutu-only version of the mod. But those are likely very hard to combine to this, so jastey hasn't invested time in trying to do that. As it likely be a waste of that resource.

Yep, Jarno Mikkola. my Mega Mod FAQ. Use of the BWS, and how to use it(scroll down that post a bit).
OK, desert dweller, welcome to the sanity, you are free to search for the limit, it's out there, we drew it in the sand. Ouh, actually it was still snow then.. but anyways.
