Ok…
This is quite unexpected.
So lets debug the problem.
Add blueprint events for fire and jump in character blueprint and print out something on each event to check if the input actually happens.
Also maybe the problem is cause by my latest update in /Config/DefaultInput.ini
Please open it and delete all the empty lines between :
-ActionMappings=****
+ActionMappings=****
If it still won’t work than I will need to re-test whole project and update the github version again.
Please post the updates as soon as you can.
