There are 2 major bugs that I found. Both can ruin your save:
1- During the Zecora scene, if you proceed with the +18 scene, you enter a loading screen that you URGENTLY need to force close the game because if you wait, it can create a super LAG that may require you to unplug your computer.
2- If you pick up the poisonous plant to start the scene of the beginning of the next day and at the same time Rainbow Dash tries to take you to her house in the clouds, both scenes will collide and you will lose all the events and appear inside Zecora's house.
This loading increases the amount of RAM every second. This is the last screenshot I managed to take before it became impossible to process the screenshot.
