Description of Bug
Bug was reported by a player on the NexusMods website, titled "Sometimes the screenshot files are empty": https://www.nexusmods.com/stardewvalley/mods/4779?tab=bugs

Expected behavior
Screenshots should always display the correct image and not sometimes be an empty file.

May be related to #30 if the move is happening after the OS creates the file but before the game locks the file for writing.

Good to know. Since that issue is fixed now, I'll contact the player who reported the bug after I've published the next update and ask them to see if they are still experiencing the problem.

Closing since this was likely fixed in #32. User who originally reported the issue never responded to say if updating solved the issue or not, but no one else has reported the bug since then.
