Hi Sam54544, sorry to hear you're having this issue.
The press-and-hold is only supposed to take about a second before it activates the action, but in your case it sounds like something is going wrong with the timing.
I'm not able to replicate the issue when I play the game myself, but looking at the code there are a couple of things I could change. I'll let you know when I have a new build posted that you can try.
In the meantime, could you share a few more details to help me narrow it down?
- Are you playing the Windows, Mac, or Android version?
- How long do you actually have to hold the button down to activate the action? Are we talking about a minute and a half? 15 minutes? Or literally half an hour?
- When you're holding the button down, do you see it filling up with blue steadily (but slowly), or is the amount of blue fill jumping around or not filling at all?
Thanks for your patience, hopefully we can get this solved for you soon!
