The latest update to the main grid servers has caused a bit of an issue with a long-used function, namely llApplyRotationalImpulse. This is a function I use for such things as shell casings on eject to give them a little bit of random spin. The error has no effect on the function of products, it just produces these annoying error messages. LL should be fixing this in a server update. Should they choose to sit on it, I'll be updating everything that uses it (which is a lot of stuff) in the near future. Many thanks for your future patience. :)
If you'd like to view the JIRA on it, and hey, throw in your votes for LL to fix it pronto, the JIRA issue is here: SCR-372
