  How are you saving the data? If you're using System Save/Load, saved games are usually compatible between versions unless you make major changes to the game, start removing, renaming objects, etc.

  If you're saving to Local Storage or to a file, it's up to you to ensure compatibility between versions.

  For example, if you're loading an item from Local Storage that didn't exist in older versions, make sure to check whether the item exists first. If it doesn't, assign it a default value.

  I suspect the problem is caused by picking by UID. If the event runs for multiple enemy instances, the "Pick instance with UID" condition won't work correctly. You could try fixing it by adding "For each Enemies" as the first condition.

  That said, linking objects by UID is an outdated approach. I'd recommend connecting sprites and hitboxes using hierarchies instead. You can do this in the event where an enemy is spawned, or even create the hierarchies manually in the editor (on an unused layout) and spawn the entire hierarchy.

  For example, creating a ZombieHitbox with the "Create hierarchy" checkbox enabled will automatically create both the hitbox and the sprite with zombie animations.

  Then, in events you can simply use the "Enemies Pick child EnemySprites" condition.

  It's very easy to make your own progress bar using a sprite or tiled background. You literally only need a single action:

  -> ProgressBar: Set width to Self.ImageWidth×progress

  Where progress is a number from 0 to 1.

  Here is a slightly more advanced example:

  It's not that complicated, just use a good text editor like Notepad++.

  You need to copy this section:

  Another option is to save the project as a folder and manually edit the layout.json file - copying "data" from one tilemap to another.

  Try setting bullet speed before setting the angle of motion.

  In fact, you should move these three actions into the parent event on your screenshot:

  Block set bullet speed
  Block set gravity
  Block set bounce off solids
  

  Then:

  ...If player mirrored: Block set angle of motion to 150
  ...Else: Block set angle of motion to 30

  Maybe these examples would be helpful:

  howtoconstructdemos.com/circular-progress-bar

  howtoconstructdemos.com/bend-a-sprite

  And yes, you can draw a dashed circle on a drawing canvas.

  Always stick to the version that works now. That's an industry-wide approach to making games.

  You will have to update sooner or later if you want to publish your game. And the more versions behind you are, the more likely you'll run into issues.

  Is your grid also isometric, as in the gif?

  This will snap the sprite to 10x10 px grid:

  Sprite On Drop
  OR Sprite Is Dragging
  
   -> Sprite set position to X: round(self.x/10)*10, Y: round(self.y/10)*10

  You link says "access denied".

  I have two example projects with a similar camera behavior, you can download them here:

  There is another (a bit more advanced) way to shorten your code into a single event.

  System HighestLevel>11 
  System HighestLevel<=160 
   -> quotes Set animation frame to (HighestLevel>122 ? 4 : HighestLevel>82 ? 3 : HighestLevel>51 ? 2 : 1)
   -> Achievements set frame to self.num

  I assume both objects has the Platform behavior?

  You can try something like this, but it may require some tweaking.

  

  Note that the first event is an OR-block - here is jumping OR hero is falling.
