CGL is a big company. Or is it a small company? I guess it depends on the what the excuse-of-the-week needs to be.
The company's small. The freelancer pool who writes all this stuff is somewhat broad, however, and while we try to talk to each other...we're not always successful.
For example: I wrote up versions of the spells One Less, Slay, and Slaughter for
Sail Away Sweet Sister. Someone else wrote the spell section for
Street Grimoire, and I mentioned this to that person. After that...I wasn't in that loop. Frankly, I didn't have
time to be in that loop because I was working on another project and had a lot more Real Life happen to me than I really needed, but that's a separate issue. The point is...we don't always coordinate like we should. And that's as much on us as it is on CGL. And we're working on it.
Another point is...sometimes people need the same thing for their work, and they don't know the other guy's working on it, and they put it together, and they both get published. This is a CGL thing, but sometimes it can't be helped. Depending on where/when in the cycle things happen, one version of a thing might be in layout or on the way out the door before the other is turned in.
We're all human. Even the guys at CGL. I'm not making excuses for anyone but myself...and believe me, I'd love things tightened up, especially if my name's in the credits or on the cover. But I accept that things happen, and I know that there's a real effort being made to make things better. Whether it works out or not is a separate question that's yet to be answered.
