Custom CSS not working anymore?

Dear Devs,

I once liked your plugin for styling the timeline view and the event pages.
But since the last 2 updates CSS-styles are messing around a little bit. And since the 1.3 update custom CSS doesn’t seem to work anymore and the complete styling-options are totally messed up.
It also looks like someone (Tribe or you guys) changed several CSS-class names, but I’m not sure.

In my attempt to fix the look of my event-calendar I also tried to copy edited styles from the titan-framework-ect-css.css into the custom css-field and to give them an !important just to overrride these ugly gradients in the timeline-view. Nothing worked. Custom CSS is been totally ignored.

Same at the event pages. I used some minor style fixes there, not working anymore. As far as I see names of CSS-classes doesn’t seem to have changed here, so why is my CSS ignored? Is it a bug or a feature?

And why is there an image in the timeline for events without an post-image? If there is no post-image defined the should be no image in the timeline for this specific event.

So could you please tell me how to get the custom CSS back to work properly?
