Under certain circumstances, the Details panel will show you the details for another var than the one you currently have selected.
This happens when you do this:
- Type some text in the “Search” field of the “My Blueprint” panel (for instance, to search for a variable). Leave your search text in the field, so only the filtered vars appear.
- Select any other variable on the graph → The Details panel displays the values for that variable. All good so far.
- Change the value of the var you selected on the graph → It gets updated. Still good.
- Select another variable on the graph → Now the Details panel shows the details for the first filtered var in the “My Blueprint” panel!
If these vars are of the same type, you WILL NOT realize anything’s wrong, and modify the wrong var’s value.
If you don’t realize it right away (you will eventually, but it might be after extensive debugging) you’re good to dig in the undo history, which won’t show you the value of the var you never wanted to change. So you have to undo up until that point, since you have to “Jump to this transaction” and can’t undo a singular action.
This is clearly a bug, and it has been driving me nuts a number of times.
Shouldn’t be too hard to fix, please have someone look at it.
