I updated to version 8.3.8 the other day and today I was creating a tag change gateway event.

Nothing fancy, just updating tags when a value changes. The issue I have is that it keeps showing me a compile error.

```python
SyntaxError:("mismatched input 'myVariable' expecting INDENT",'',3,1,'system.db.execQuery('mypath', {"mycolumn":1}, "myProject")\n')) 

```

The problem is if I save it anyway it works fine, if I add anything to the script I get the error.

If I remove everything from the script and just type pass I get the same error. is this a possible bug?

```python
if not initialChange:
    pass

```

Has anyone else seen this behavior?

Then I upgraded to 8.3.7 and went into the script to add something and when I try to close & save I get a compile error. The other crazy thing is that I don't think I should be getting a compile error because the error is complaining about indent and my indent looks fine to me. Since the code is on t…

Thanks, it makes it difficult to troubleshoot.
