Replay Mod Forums

I've added two time keyframes 37 minute & 38 minutes at 0 & 32 seconds on the timeline respectively. Then I add two spectator keyframes for the same player at the same two moments in the timeline. When double clicking on the spectator keyframe I can change the values but cannot click Save, Cancel, Next/Prev or press Esc.

Forge - 11.14.3.1450
ReplayMod - 1.0.7
Java - 1.8 (MacOS X Loader version)

It looks like the Save does work (if I change the spectating method to shoulder camera and click save the timeline changed from blue to orange) but the window doesn't close.

Edit:

Error message from log window whenever a button is pressed:-
