I doubt it is my system, 0.5.2.4c worked just fine and was the last build I played. No, I am not running an outdated save, either. I started a new game. My graphics are Invidia based, not Intel, and I used to play 0.5.2.4c on a machine that only had Intel's integrated graphics on a far weaker i3 processor.Unless you have mods installed, chances are high that you are having troubles as a result of your system or hardware, as the game is quite stable with almost no hanging or crashing. There are 2 points where the game loads a massive amount of files into memory and can hang the game momentarily: the start and manual portrait selection. The most recent version 1.0d fixes several bugs and errors, but none of them sound like your issue.
The only significant action that comes to mind that occurs at all of the times you mentioned is posting of infotext to the right side of the screen, which is a GUI object that tends to have problems when the computer does not support the graphics. The Godot Engine has a history of problems with Intel integrated graphics and occasionally doesn't play nice with certain graphics drivers.
In case you wish to check for errors. For most systems(prior to v1.0d), the game starts with 2 windows: a game window and a console window that reports errors. The console is the easiest way to check for errors, though v1.0 does include the setting to enable file error logging.
It isn't mods for sure since I'm running the game as it comes from the OP.
It could be that something in my copy got messed up somewhere in downloading or extracting, that's the only possibility I can think of that is both feasible and not specific to a version of the game or to my system.
EDIT: Further information acquired, alt+tabbing to try and get to the console window results in the game window reverting back to the age warning that pops up when you first open the game despite being in the middle of a save. This is DEFINITELY a bug at this point and it IS game breaking, but it can be worked around by saving constantly. It is also consistently crashing around the Sebastian market encounter early in the main quest with the youth and maturity potions. In other words, I can no longer continue the main quest after interacting with him there, it freezes every time. I do still believe this is potentially in my copy, that something got messed up in transit.
