Older LVs had this problem as well, here is a portion of an article you might find helpful:
Pocket Lining (yes, THAT problem)
It is no exaggeration to say that every Louis Vuitton owner in Japan has experienced a "rotten" pocket lining. Not the cross-grain leather lining, but the smooth lining used for pockets. It is NOT genuine leather but synthetic! Damaged pocket linings are described as "melted", "sticky", "peeling", or "flaking". This is caused by the humidity. The moisture in the air is retained inside the pocket lining where it does not vent (naturally). The water "rots" while being retained in the material, and this causes the stickiness. Then the water evaporates as the weather dries, and that causes the peeling and flaking. In the worst case, both front & back of the pocket linings are this synthetic leather (like inside pockets), and the pocket ends up being shut as the material melts and dries like glue. Nothing you can do but have them replaced by Louis Vuitton (expensive). You really need to air & air & air the pockets, especially in storage, to avoid this problem.
Louis Vuitton changed the material a couple of years ago to supposedly take care of this problem for their new productions, since they ended up having to face tons of VERY UNHAPPY Japanese, who had the lining replaced one year and have to do it again the next year. They tested this new synthetic material in South Asia where the weather is extremely hot and humid. It seems to have been improved, but even this new synthetic lining isn't problem free. I've had reports that it still rots in Japan.
