We had to make few changes to the SC Angelscript API as a result of some bug fixes. This will be effective as of the next version of Sven Co-op (5.11). If your script(s) use any of the changed class members/methods, it won't work anymore in SC 5.11 and needs to be updated. You can find more details and a list of upcoming changes here:

We'll gladly help you, should you have trouble with the changes. You can reach us on our main forums or our Discord server (#scripting channel).
