No barrier on first turn during explosion

Platform, device version and operating system:

Any version of Android, any devices.

What you were expecting to happen, and what actually happened:

Let’s say I use mountain crusher, Titan class with Rock Solid talent activated.
At the beginning of the fight, if an explosion occurs ( like with potion ) and gives a match 3 or more brown in the cascade following the explosion DO NOT give me barrier, I must do a match 3 brown myself later, basically loose 1 turn in the process to have my barrier.

How often does this happen? When did it begin happening?

Always happening, since 4.5 I guess.

Steps to make it happen again

Use a class with Rock Solid talent activated, start a fight with an explosion potion, if a match 3 or more browns occurs during the explosion, your hero won’t have any barrier, to have the barrier you must do another brown match 3 by yourself later.
