Nodemcu crashes when FIRSTFLOOR_LEDS set to 50

[Warsenius]

Hi,

first of all, thanks for all your videos on your yt channel !
I am testing with your code on a nodemcuESP8266 board.
When i set FIRSTFLOOR_LEDS to a lower number like 50 the board crashes repeatedly when using certain effects like 'Fire'.
This is what i see on the Serial Monitor:

When i set it back to the default number it runs fine.

if i set the SECONDFLOOR_LEDS to 50 it never crashes even on fire, however the color of the fire effect turns Green, while on the default LEDS count its red.

I believe this is caused by the fire effect generating a number greater than 50 and then calling it, but the LED doesn't exist in the matrix which causes a crash. Perhaps I should add in a comment to have a minimum number of LEDS per matrix.
