A quick search for "rst tmbundle" in Google brought up this TextMate bundle which should work:
Is this still a problem for you? I cannot reproduce this anymore on iOS 9.3.2.
Do you see any messages in the Console app when this happens?
This is just a wild guess, but maybe it is trying to open a remote file that it can't reach anymore?
~/Library/Containers/com.textasticapp.textastic-mac/ Data/Library/Saved Application State/com.textasticapp. textastic-mac.savedState/
Deleting this folder should remove all saved window state so that it isn't restored on the next launch of the app.
I don't think that's possible with how the system currently works.
I see, thanks for the explanation. That makes it easier for me to build a test scenario.
I'm curious: what do you use the symlinks for in your project?
I can confirm that the stable channel of Firebug Lite does not currently work in Textastic 6 on my iPad.
But, when I open the website https://getfirebug.com/firebuglite in Safari on my Mac, I have the same problem: there is Firebug Lite at the bottom of the screen, but it doesn't respond to mouse clicks.
So it looks to me like this is a bug in the current "stable" version of Firebug Lite.
The good news is: the "debug" channel works! If I use this markup instead, it does work for me:
<script type="text/javascript" src="https://getfirebug.com/firebug-lite-debug.js"></script>

Currently not, sorry.
To work properly, code completion for SQL would probably need to be able to connect to an SQL server so it can complete table and field names. This is out of the scope of Textastic.
