Hard to say for sure.  When they reduced the rewards from the "new start" xp event they did not notify us.

I think they thought we would not notice it changed.

This might be another instance of palarium offering another reward to get us to burn resources and work on the event - only to remove the rewards after it starts.

They have lied and decieved us in recent past - hard to know if they are at it again or if it is just ANOTHER bug as the game has sooo many now.

Es un bug y los desarrolladores lo están mirando desde anoche (horario de España).

It is a bug and the developers are looking at it since last night (Spain time).

Other bug?? what a surprise lol

It seems that all errors are for subtraction, but there are never any errors for addition.

Hello!

The issue was a visual glitch and its solved by now. 

You will get the right rewards. Enjoy!
