Yes, the error seems to be from this section, which uses the new animations curve feature to ease in/out motions. This section works completely fine normally, but causes a fatal error when GMLive is running. Seems like GMLive is working for everything else as normal though :
var _curveStruct = animcurve_get(Ease_InOut); var _channel = animcurve_get_channel(_curveStruct,"x"); ease_value = animcurve_channel_evaluate(_channel,curve_pos)
