Module development and code questions

I'm receiving an incorrect Current Path after I return from a submit function in a form and not sure why. Here's the details.

I have a custom route /picture-game that renders the PictureGameForm and the route is loaded in an Ajax Dialog Modal.

I installed the following module on my site :

https://www.drupal.org/project/form_mode_manager

I have created an "Input Modes" in "Display Modes" for the store type with the machine name commerce_store.shipping_methods

/admin/structure/display-modes/form

I created a custom module to automatically flag stores that are updating.

Is there a way to block some 3rd party cookie in a website?

Does anyone know how to configure this module in drupal 7?

Hope to see a comment.

I have a form that is used to play a game (users select between one of two images multiple times) that utilizes a service class that manages loading images, calculating results, etc. How can I instance this service class one time so that it doesn't get re-instanced every time I rebuild the form, do you have to do it in form_state?

I was trying to do it in `__construct` because I thought that was only called when you first instanced the form, but when you rebuild the form it gets called again so my service class gets re-instanced. 

The default Drupal logger is so inefficient it can't even print out an array containing two content-types, what gives? I'm trying to log an array that contains two content-types but I keep getting the error that I've ran out of memory, which is ridiculous because I currently have my setting at `512M`. 

It seems crazy to me that it takes Drupal more than 512MB to log some text....
