I looked at it.

One problem is that the entity number seems to be set incorrectly on action 24. It should be 240, not 301.

the entity for the dynamite objectives should be the trigger_objective_info entity number. Sometimes its a bit tricky to get, but you can move the crosshair around a bit until you get it.

Also, for the node_connect in the script for action 24, it seems that it should be:
node_connect 173 190 true

I think that should solve your problems.

A tool that I use for troubleshooting possible group issues is the command /goal_num

This will display the current group that the AI is in.

Hope this helps
