Hi OC_alexm2206,
Sounds strange. Are you getting any errors or warnings while running that level?
Just some suggestions: make sure your Level Blueprint is parented to the ‘Level Script Actor’ class or an derivative of that class. Try to run a ‘Print String’ node on ‘Begin Play’ and add a breakpoint on the ‘Print String’ node (you can add one one by selecting a node and hit F9). The game should pause upon reaching the breakpoint, if it does the problem is somewhere else.
