Okay; maybe not a big, notable one.
I was messing around with my companions plugin the other night, converting it to a master to check out some script changes I had made; when I noticed this in TESSnip:
For those of you who aren't used to reading esp headers, I'll point out the important bit: seven thousand and eighty four records in the plugin. The last time I mentioned how big the plugin was getting was back in May; when it stood at 5789 records -- that means that in the last six months and a week or so, I've added one thousand, two hundred and ninety-five new records to the plugin.
For reference, v5.65 of the RR Companions Vault -- considered by many to be a fairly big mod -- has 5820 records.
So yeah... I think that whole "smaller, sleeker system to run my personal companions" crap has gone right out the window at this point.
On the up side, though: the mod, big as it is, still maintains a zero conflict rate; and is extremely reliable as long as I'm not trying to get it to do something the engine doesn't like.
