Most often it happens because of using sampfuncs based opcodes without having sampfuncs plugin added to the Sanny Builder files. Solution:
http://ugbase.eu/Thread-ASI-SAMPFUNCS-5-3-0-3-7springfield said:sf_5_X_X_sdk.zip : contains both the dev. files for CLEO and C++ API.
- Copy all files from the "SB data" to "/Sanny Builder 3/data/sa".
