Transport Tycoon Forums

I have an odd problem I can't seem to solve. When loading a saved game, I am greeted with "invalid train length" errors and disabled GRF files. Here's what I have:

Combined North American Signals 1.1
Generic Tram Set 0.4
Industrial Stations Renewal 0.8.0
Multi-Storey Car Park
New Transmitter for TTD
Oil-Fired Power Station
US Stations Set 0.86
US Town Names 0.31
US Train Set 0.87.4 (disabled)
Water Treatment Plant (disabled)

The climate seems to make no difference; I've had this problem both in the mountainous and desert climates. When I initially start the game, there are no problems. Its only on loading a saved game that the GRF files are disabled.

Anyone know what I'm doing wrong here?

I'm using version OpenTTD v0.6.3 in Debian Etch

0.6.3 is more strict about NewGRFs doing invalid things (according to the specifications). Most likely your issues are caused by the extra strictness. As I don't have the exact NewGRFs you have I can't tell for sure.

My mistake - I was sharing savegames between two Linux boxes. I updated one from 0.62 to 0.63 and left the other at 0.62.
