Plutonium

Hello everyone. Today Plutonium just got updated to version r5106. After the update, when I try to play the 4 zombies map solo I get the error shown in the picture. Not to mention none of the custom zombies map launch anymore. Can somebody help?
Edit: the console shows this as the error:
******* Server script compile error *******
Error: unknown function: @ scripts/sp/zm_spawn_fix::checkforalldead
