Ok, here's the deal:
I start up a server but I find that some of my selected addons are missing. This is because I get this message:
Error: SimDataBlock::onAdd() - Exceeded maximum number of data blocks (4095)
Apparently I can't have more than 4095 datablocks. What's confusing is that I've had many, many more than 4095 before this. What's going wrong? Can I increase the limit?
