Made my first wedding cake yesterday

this semi naked cake.

i took it to venue to assemble at 12.00

weddimg was at 1.30

it was 28 degrees here. The wedding was in a marquee ! It was stifling. I kept telling them it was too hot 

no air con. They put a fan on it, but it kept going off.

i left it not happy with the heat- I messaged the bride, sister and mother telling them to keep an eye on it because it was too hot.

i just heard that the venue turned the fan off and left it!

it collapsed. I'm heartbroken and feel at fault!
