Limit of 15 routes in module.routing.yml I have see when i want to create a new route they have an limit of 15 routes per module. In fact i have created an over route an i'm suprise to see of my road wans in route:debug. However they are in the module.routing.yml 

I have cout the number of routes i have , and after 15 the routes arren't seen. 

It's me or it's normal?

The YAML file : 

 //empty line is not comment on the code
 unicef42.unicef_controller_index:
   path: '/unicef42'
   defaults:
     _controller: '\Drupal\unicef42\Controller\UnicefController::world'
     _title: 'Unicef controller'
   requirements:
     _permission: 'access content'

 //...the other routes

 //The 15th routes , no comment in the real code,1 empty road between the 14th and the 15th routes
 unicef42.accueil_controller_index:
   path: '/accueil'
   defaults:
     _controller: '\Drupal\unicef42\Controller\AccueilController::index'
     _title: ''
   requirements:
     _permission: 'access content'

 //The 16th routes , no comment in the real code, 1 empty road between the 15th and the 16th routes
 unicef42.accueil_controller_index:
   path: '/accueil2'
   defaults:
     _controller: '\Drupal\unicef42\Controller\AccueilController::index'
     _title: ''
   requirements:
     _permission: 'access content'
 //empty line is not comment on the code
It's just you I'm afraid.

Take the system module's routing file for example; there are a few dozen routes in there, plenty more than 15.

Symfony doesn't impose any limits either, so I'd check that your YAML code is properly formatted and valid. If you're positive it's all good, you've probably hit a bug and the best course of action would be to report it.
