During our final check of the 2.40 update, we noticed a couple of bugs relating to some sprite errors on the Ouginak class and a few missing sound effects. We have already scheduled a fix for these problems on February 21 (the next scheduled weekly maintenance).
Please do let us know if you find other bugs and we'll let the team know ASAP!
Edit: We have temporarily disabled access to all paddocks while we fix a bug that causes mounts to lose babies. We know this is a bother to you all, and we're working to correct it as quickly as we can. We apologize for the hassle.
