I reported this bug last time, but I finally figured out what causes it, so I'm here to report it again.

Issue: For a channel, calling ObjectGetValueByTime with line_id=1 returns an incorrect value if you check the object type beforehand using ObjectGetInteger instead of ObjectType.

I hope you guys look into it because there's no way to call ObjectGetValueByTime on multi-line object in another chart if you need to check the object type.

Here's the code, I left a comment for you to alternate between the commented and uncommented lines to check for yourselves.

To test it, just create an Equidistant Channel, select it, then move it around. It will make a Comment displaying the price. You'll see that the bug displays a wrong value.
