Any idea what can be causing it or how to fix it?

At first I though It was caused by a deployer trying to deploy an alchemy bag, but I added the alchemy bag id (27306) to the deployer's ban list and I'm still getting the error.

Thanks in advance, jjssman.

Fixed.

How did you fix this ?

[jjssman]

Here's how I fixed it:

1- Whitelist the server or activate some kind of maintenance mode.

2- Change the alchemist bag id in Redpower's config to a different one, for example the alchemical coal one.

3- Change the alchemical coal (for example) id to the alchemist bag id.

4- Restart the server and load the chunks around the spawn so the alchemist bag (now alchemical coal) gets deployed.

5- Change the ids back to normal and restart the server.

6- If everything works you can turn off the whitelist again, if not, try again loading more chunks.
