The case of the dissapearing layer!

A few times I've loaded up the map I'm making and some of the textures I've painted on have dissapeared.I currently have two layers and they have only dissapeared in some places, not comlpetey.
I noticed the last time it happened was just after updating my lightmap so I was wandering if it's anything to do with this.
Not a major problem, I could complete the map create a lightmap and then add the textures, but I like to see how my route is looking so having both thesein situ are usefull.
Any ideas?

I too have encountered this problem, it can be rather frustrating especially when you have at least 20 tiles to repaint. If anyone could give some insight to the cause or a possible recovery of this?

Thank you for the hint with the lightmaps! Perhaps this may be the solution...?

Yep that was my thinking ts not a major issue but repainting the same tiles several times is a wee bitty tedious
