At long last, a new version of Decal has been released. This release is considered mandatory by the Decal Developers and older versions will no longer be supported as a result. In other words if you choose to continue using another version of Decal you will be OYO (okay we're likely to just have you upgrade and try and repro your problem).
The release notes read as follows:
The product of a longer than usual release cycle, Decal 2.5.0.1 is now released in it's final form. If you are a Decal user, changes to the network message processing system you MUST upgrade to this version. All other versions are deprecated as of today, and no support will be provided for them. Although older releases will appear to work correctly for a time, they may suddenly stop functioning, or behave strangely - Please, all users: Upgrade to 2.5.0.1.
- The Character Statistics filter will no longer crash if you switch characters too quickly.
- ACHooks has received a cleanup, and some new hooks for developers to take advantage of.
- Add 'mask' option for vectors to handle animation packet. Messages which take advantage of this will no longer function with Decal versions prior to 2.5.0.1.
- IPluginSink fix - if Decal never accepted your command line input, it should now.
- .Net plugins will now show their version in the agent, rather than the version of the .Net COM proxy.
