Did the alien invasion blow up one of Wick's rail lines, or was it just coincidentally unfinished?
the invasion did break a few lines.... I have tried to fix them in vain periodically, but never enough time, or patients to do so
Yeah, after further inspection an underwater ship totally smeared Wick's line going to the spawn ... fortunately that was relatively redundant since my Pumpkin Freeway can get you from A to B. It looks like someone had done about 75% of a replacement tunnel. I could have finished it off completely, but I decided to get it to about 90% and then just link them up with a walking path and add some "thematic" signs. I would be tempted to add some more alien invasion decoration to the detour tunnel if I thought it would get literally any visitors
But that was the only rail line from Wick's hub that seemed to be damaged. There is another one that dead-ends, but I'm pretty sure he just never finished it. It's way too deep to have been hit by the aliens. Pumpkin Freeway, Sea & Sky Road, Kojiiriin Expressway, and Wick's REALLY old line going to Stefl's area all still looked OK to me. Are you sure there were other rail lines that the alien invasion damaged?
P.S. Speaking of damage and Stefl's old area, I saw some damage that looked sort of like a creeper explosion, only some fences were on fire. Is it possible for Creepers to start fires, or what else could have done it? Lightning, maybe? It definitely can start fires per the wiki, but it doesn't cause craters. Wiki sez "If an explosion has the ability, it randomly starts fires in ⅓ of all destroyed air blocks" but I don't see anything about what explosions have "the ability". Could be creeper and then lightning I guess...
