So I was playing the mission “Clear Cut” on CSX Sand Patch Grade. After i sent my gp38 to couple to a manifest train, I then take an AC4400CW over to the refueling station. I get out and refuel the train. I then am asked to get back into the train. I go up to one of the steps and it wouldn’t let me climb onto the train. I tried all 4 steps on the train and it didn’t work. I then try getting on the other AC4400CW on my consist and it works just fine. I try using the crossing between both AC4400CW’s to get on but it wouldn’t let me. UPDATE: So I was able to figure out why this bug was occurring. (I may be incorrect) I believe what happened to me when the bug occurred was I forgot to put the fuel cap on the locomotive after it was done refueling. If it’s not a bug, then I think the game should remind us to remove the fuel loader and put the fuel cap back on
