I think the easyest way to possibly fix this is to, go into your Steam>Tools>BO3 MOD TOOLS>Properties>Local files>Verify files integrity, then, probably Steam will download some files and your Speed Cola prefab will be fixed (if the prefab was really the problem), hope I helped

sorry for my trash english.

OBS: If you search in Google "How to verify files integrity Steam" you will find a tutorial in Steam support teaching you how to do this better than I teached and with a better english
